Question

This equation is to long. I have to take a picture because my keyboard doesn’t allow me to type certain characters Given: f(x)={9x+5 if x< 0 4x +9 if x> 0 -

Answer 1

SOLUTION:

Given the function;

(a)

$\begin{gathered} f(-4) \\ \\ f(-4)=9(-4)+5 \\ \\ f(-4)=-31 \end{gathered}$

(b)

$\begin{gathered} f(x)=4x+9 \\ \\ f(0)=4(0)+9 \\ \\ f(0)=9 \end{gathered}$

(c)

$\begin{gathered} f(x)=4x+9 \\ \\ f(1)=4(1)+9 \\ \\ f(1)=13 \end{gathered}$

(d)

$\begin{gathered} f(-100)+f(100)=9(-100)+5+4(100)+9 \\ \\ f(-100)+f(100)=-486 \end{gathered}$
