Question

Find each value if f(x)= -3x+2 f(y) f(-a) f(2w)

Answer 1

$f(x)=-3x+2$

f(y):

$\begin{gathered} x=y \\ f\mleft(y\mright)=-3\left(y\right)+2=-3y+2 \end{gathered}$

f(-a):

$\begin{gathered} x=-a \\ f\mleft(-a\mright)=-3(-a)+2=3a+2 \end{gathered}$

f(2w):

$\begin{gathered} x=2w \\ f(2w)=-3(2w)+2=-6w+2 \end{gathered}$
