Question

f(x)=(2x²-8)
g(x)=6(x²+3x+2)​

Answer 1

Answer:

I) f(x)=(2x²-8)

= if x =2 then f(x) =f(2)

=f(2)=(2.2²-8)

=2.4-8

=8-8=0

ii) g(x)=6(x²+3x+2)

= if x=2then g(x)=2

g(2)=6(2²+3.2+2)

6(4+6+2) {therefore 6,6

Answer 2

Answer:

If f(x)=2$x^{2}$-8

2$x^{2}$/=8

$x^{2}$=8/2=4

x=$\sqrt{4}$=2

therefore,g(x)=6$x^{2}$ +18x+12

                 g(2)=6(4)+18(2)+12

                 g(2)=96
