Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function </u>
If y=f(x), the inverse function is defined such as
To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c)
In our case,
a) Interchanging letters
b) Isolate
c)
As we can easily see, f and its inverse are exactly the same
Given :
Length of one of the equal sides of an isosceles triangle = 3x+2
Then, length of the other equal side will also be = 3x+2
Length of the unequal side of this isosceles triangle = 14
Formula for finding the perimeter of an isosceles triangle :
A formula for finding the perimeter of this isosceles triangle :
Bringing all like terms together we get :
Thus, the formula = 6x+18
Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
