How To Find The Range Of A Function

Hi friends, in this blog we will see How To Find The Range Of A Function. Function is taken to show a association between set of inputs values and set of outputs values in such a way that every value of input is associated to exactly one value of output. Let we have a function f (r) = r / 6 (f of ‘r’ is ‘r’ divided by the value 6") is a function. So if we are going to put the value of ‘r’ as 6 then we get the value of function as 1, it can be written as: f (6) = 6 / 6 = 1,

Now we will understand how to calculate range of a function. In function, all the ‘y’ coordinate values are said to be range of a function. In the same way we can also find out the domain of a function, all the possible terms of ‘x’ coordinate are known to be domain of a function. Let we have given some values (12, -18), (-71, 84), (53, -42), (-25, 17), then range of function is all the ‘y’ coordinate terms.

Domain = 12, -71, 53, -25.

Range is all ‘y’ coordinate values,

Range = -18, 84, -42, 17.

Let's understand that how to calculate the range of a function. Some steps are taken to calculate the range of a given function which are shown below:

Step1: To calculate the range of a function first have to take a function which contains ‘x’ and ‘y’ coordinates.

Step2: As we discuss above the range of a function is all ‘y’ coordinates values.

Step3: In above function the terms of ‘x’ and ‘y’ coordinate are there then we can easily calculate the range and domain of a function.

In this way we can easily find out the range of a function.

How To Find The Range Of A Function

Range is the difference between greatest data value and least data value.
Suppose there is two set of data value first  one is X( a,b,c,d) and second one is Y(p,q,r,s).
If a function ‘f’is defined from set X to set Y then for f:X->Y , set x is called the domain of function f and set y is called co-domain function of f. The set of f images of the elements of x is called the range of function .
So in this case
Range = p,q,r

How to find the range of a function
#The easiest way to the range is on the graph. The range of the function is the range of y values it enclose.
#If domain is given, the range is the range of y values  corresponding to x values in the domain.
# check if function repeats. Any function which repeats along the x-axis will have the same range for the entire function.
Example: sin(x) has a range of -1
#The domain of a function’s inverse function is equal to that function’s range.
#Take a derivative of the graph. Find the y values at these points and the ends of the domain and take the most extreme ones as the boundary of the range. (know more about Range, here)

 Example: find the range of the function : g(x)= x/3+5 if the domain is -6,-3,0,3,6
Solution: we know that domain is the values x takes. Range is the corresponding values of the function takes.
Here g(x)= x/3+5.
For example when x=-6,we get -6/3+5=3
When x=-3, we get -3/3+5=4
When x=0, we get 0+5=5
When x=3, we get 3/3+5=6
When x=6, we get 6/3+5=7
So the range is (3,4,5,6,7)

Q = mc delta T
Where Q is amount of heat needed
M is the mass
C is specific heat capacity
Delta t = temperature difference.
