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 $f(2)=-8$

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 $f(2)=-8$
