Question

y= (x - 3)^2 when x = 9

Answer 1

when x=9, y=36

Explanation

Step 1

this function is a relation where y depends on x, then to find y you need you to replace the value for x in the equation with the given value(9)

Hence

$\begin{gathered} y=(x-3)^2 \\ \text{when x=9} \\ y=(9-3)^2 \\ y=(6)^2 \\ y=6\cdot6 \\ y=36 \end{gathered}$

then, when x=9, y=36.
