Given that:
h(x) = x^3 + x
g(x) = 2x+ 3
We need to find g(h(2))
First we will determine the values of h(2).
==> h(2) = 2^3 + 2 = 8+2 = 10
Now we will substitute into g(h(2)
==> g(h(2)) = g(10)
Now we will substitute into g(x).
==> g(10) = 2*10 + 3 = 23
==> g(h(2)) = 23

We have the two functions h(x) = x^3+ x and g(x) = 2x + 3.
Now we need to find g(h(2)).
h(2) = 2^3 + 2
= 8 + 2
= 10
g(h(2))
= g(10)
= 2*10 + 3
= 20 + 3
= 23
Therefore g(h(2)) = 23.
