2. a=2, b=3, c=4, d=6.

3. a = 9, b = 3.

Step-by-step explanation:

3) g(x)= x3 + x<br> h(x) = x + 4<br> Find g(0)h(0)

Arte-miy333 [17]

Answer:

$goh(x)=x^3+12x^2+49x+68$

Step-by-step explanation:

$g(x) = x^3+x$

$h(x)=x+4$

We have to find

$goh(x)$

$goh(x) = g(h(x))=g(x+4)$

If $g(x) = x^3+x$

$g(x+4) = (x+4)^3+(x+4)$

= $x^3+12x^2+49x+68$

Hence our answer is

$goh(x)=x^3+12x^2+49x+68$
