F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.

Answer:
-2c^2 + c
Step-by-step explanation:
The question is also the same as asking what is the x value of the solution of the two functions graphed above. The solution is the point where these lines intersect. So, from the choices, the correct answer would be the second option. The input value that <span>produces the same output value for the two functions on the graph would be x=-2. Hope this answers the question.</span>
Step-by-step explanation:
simplify the ratio
ex: 15:20
3:4
then change the ratio to a fraction
ex: 3:4
3/4
then change a fraction to a percent
ex: 3/4 =75%
