Find the value of f (x)=x²-4 and g(x)=3x+2 Find the value of f (-1)g(-1)

mrs_skeptik [129]

Answer:

Step-by-step explanation:

$f(-1)g(-1) \text{ is the same thing as } f(-1)\cdot g(-1). \\\text{Therefore, find f(-1) and g(-1)}$

$f(-1)=(-1)^2-4\\f(-1)=1-4\\f(-1)=-3$

$g(-1)=3(-1)+2\\g(-1)=-3+2\\g(-1)=-1$

Therefore:

$f(-1)\cdot g(-1)\\=(-3)(-1)=3$
