Question

I need help with my assignment. It has three questions

Answer 1

Let's evaluate the following expression

`f(x)=-x^2+8x-2`

x = -3

`\begin{gathered} f(-3)=-(-3)^2+8(-3)-2 \\ f(-3)=-9-24-2 \\ f(-3)=-35 \end{gathered}`

x = 5

`\begin{gathered} f(5)=-(5)^2+8(5)-2 \\ f(5)=-25+40-2 \\ f(5)=13 \end{gathered}`

x = 0

`\begin{gathered} f(0)=-(0)^2+8(0)-2 \\ f(0)=0+0-2 \\ f(0)=-2 \end{gathered}`

x = 2

`\begin{gathered} f(2)=-(2)^2+8(2)-2 \\ f(2)=-4+16-2 \\ f(2)=10 \end{gathered}`

x = 7

`\begin{gathered} f(7)=-(7)^2+8(7)-2 \\ f(7)=-49+56-2 \\ f(7)=5 \end{gathered}`
