Use symmetry to graph the inverse of the function

The correct option is d.

Step-by-step explanation:

Let a function is f(x) and its inverse is f⁻¹(x). If both functions drawn on a coordinate plate than the graph of f(x) and f⁻¹(x) are mirror image of each other across the line y=x.

In other word the line y=x is the axis of symmetry of the graph of function and its inverse.

We need to find the correct graph that represent the function and its inverse.

Draw a line y=x in each graph as shown below.

From the below graph it is clear that only graph d represent the function and its inverse because both the functions are mirror image of each other across the line y=x.

Therefore the correct option is d.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
