Question

Graph the functions on the same coordinate plane.

Answer 1

Answer:

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

-2

-1

Step-by-step 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

Answer 2

Answer:

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
