Answer:
[tex]h(3)=30[/tex]
Step-by-step explanation:
We have the polynomial:
[tex]h(x)=x^3+2x-3[/tex]
[tex]h(3)[/tex] means that we have to replace in the polynomial [tex]h(x)[/tex] with [tex]x=3[/tex].
Then,
[tex]h(x)=x^3+2x-3\\h(3)=3^3+2.3-3\\h(3)=27+6-3\\h(3)=27+3\\h(3)=30[/tex]
We obtain that the polynomial h(x) with x=3 is 30.
[tex]h(3)=30[/tex]
