Answer:

1. x = -6

2. x = 9

Step-by-step explanation:

To find the zeros of each function we need to make f(x) = 0 and solve for x.

So, for the first function, we get:


\begin{gathered} f(x)=2x+12=0 \\ 2x+12=0 \end{gathered}

Then, solving for x, we get:


\begin{gathered} 2x+12-12=0-12 \\ 2x=-12 \\ (2x)/(2)=-(12)/(2) \\ x=-6 \end{gathered}

In the same way, for the second function we get:


\begin{gathered} f(x)=3x-27=0 \\ 3x-27=0 \end{gathered}

Solving for x:


\begin{gathered} 3x-27+27=0+27 \\ 3x=27 \\ (3x)/(3)=(27)/(3) \\ x=9 \end{gathered}

Therefore, the zero of the first function is x = - 6, and the zero of the second function is x = 9.
