Question

Please be quick! i need answer for each in the box, giving 15 points

Answer 1

The solutions are
`f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3` and
`f(2)=-8`

Step-by-step explanation:

To find the values of f(x), we need to substitute the values for x in the function
`f(x)=2-5x`

For
`x=-2`,

`\begin{aligned}f(x) &=2-5 x \\&=2-5(-2) \\&=2+10 \\&=12\end{aligned}`

Thus,
`f(-2)=12`

For
`x=-1`,

`\begin{aligned}f(-1) &=2-5(-1) \\&=2+5 \\&=7\end{aligned}`

Thus,
`f(-1)=7`

For
`x=0`,

`\begin{aligned}f(0) &=2-5(0) \\&=2+0 \\&=2\end{aligned}`

Thus,
`f(0)=2`

For
`x=1`,

`\begin{aligned}f(1) &=2-5(1) \\&=2-5 \\&=-3\end{aligned}`

Thus,
`f(1)=-3`

For
`x=2`,

`\begin{aligned}f(2) &=2-5(2) \\&=2-10 \\&=-8\end{aligned}`

Thus,
`f(2)=-8`

Hence, the solutions are
`f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3` and
`f(2)=-8`
