Find the value of h(2)

Question

H(x)=2x+3x+5

Find the value of h(2)for me please.

Answer 1

H(2) = 2(2) +3(2) + 5 = 4+6+5 = 15

just replace x by 2

I can't help but wonder though, if the original function wasn't H(x) = 2x^2 + 3x +5. IF so, then

H(2) = 8+6+5 = 19

the equation is usually in order of descending powers of x, suggesting the lead term might be 2x^2 not 2x
