Question

Graph the functions on the same coordinate axis.=S f(x) = 2x + 11 g(x) = x2 + 2x – 8

Answer 1

(-3, -5) and (3, 7)

Explanation:

We have the following functions:

`\begin{gathered} f(x)=2x+1 \\ \\ g(x)=x^2+2x-8 \end{gathered}`

To determine the solution of a system of equations graphically, we must graph each function, and the intercept(s) would be the solution of the system.

We graph and determine the solution just like this:

Therefore, the solutions of the equation system are:

(-3, -5)

(3, 7)
