Question

find the inverse for the function:

\\f(x) = -3x + 15\\

\\f^{-1}(x) = -\frac{x}{?} + \quad\\

Explanation:

Replace function notation with y

Using the Finding Inverse Algebraically knowledge point

$$ y = -3x + 15 $$

Swap variables x and y

Using the Finding Inverse Algebraically knowledge point

$$ x = -3y + 15 $$

Solve for y

Match with the given template

Using the Linear Inverse Functions knowledge point

$$ f^{-1}(x) = -\frac{x}{3} + 5 $$

Answer:

Find the inverse for the function:
\(f(x) = -3x + 15\)

\(f^{-1}(x) = -\frac{x}{}\)<blank>3</blank> + <blank>5</blank>
