Question

Graph the functions on the same coordinate plane.

f(x)=x^2+6x+8
g(x)=−x^2+4


What are the solutions to the equation f(x)=g(x)? select each correct answer
-2
-1
0
2
3

Answer 1

x^2+6x+8=-x^2+4

2x^2+6x+4=0

(2x+4)(x+1)=0

2x+4=0 and x+1=0

x=-2 and x=-1

Hope I helped!

Answer 2

Solutions to the equation f(x)=g(x) are:

-2

-1

Explanation:

We graph the functions:

f(x)=x²+6x+8

and g(x)= −x²+4

The solutions of f(x)=g(x) are the x-coordinate of the points where f(x) and g(x) meet.

Hence, solutions to the equation f(x)=g(x) are:

-2

-1
