Answer:
x = -2 and 1
Step-by-step explanation:
Given :
f(x) = x+2
g(x) = -x²+4
The solution to the equation f(x) = g(x)
=> x+2 = -x²+4
=> x²+x = 4-2
=> x²+x -2 = 0
By factorisation
=> x²+2x-x -2 = 0
=> x(x+2) -1(x+2)
=> (x+2) (x-1)
x = -2 and 1
THIS ANSWER IS FOR f(3):
f(x)=x+3
f(3)=3+3
f(3)=6
THIS ANSWER IS FOR f(-2):
f(x)=x+3
f(-2)=-2+3
f(-2)=1
