Question

Solve the following system by graphing and approximately the solution(s). Show the points of intersection when graphing by hand. Then chose from among the points below a point intersection between the two functions.

y = x² + 2x
y = 2x + 4

(2, 8)
(0, 0)
(-2, 4)
(0, 4)

Answer 1

(2, 8)

Explanation:

we have

`y=x^(2) +2x` ---> equation A

`y=2x+4` ----> equation B

Solve the system by graphing

Remember that the solutions are the intersection point both graphs

using a graphing tool

The solutions are (-2,0) and (2,8)
