Question

Please help me understand this question, i’ve been struggling with this for 10minutes!

Answer 1

Given that, for x>3, f(x)=-1.

Therefore, f(5)=-1.

Also, given that for x=3, f(x)=-2x+2

Therefore,

`\begin{gathered} f(3)=-2(3)+2 \\ f(3)=-6+2 \\ f(3)=-4 \end{gathered}`

Therefore, f(3)=-4.
