Explanation
For the expression
[tex]h(x)=2.3x^3+0.01x^2[/tex]To find the value of h(x) when x=1
we will put x =1 into the expression
[tex]\begin{gathered} h(x)=2.3(1)+0.01(1) \\ h(1)=2.3+0.01 \\ h(1)=2.31 \end{gathered}[/tex]When x=2
we put x=2 into the expression
[tex]\begin{gathered} h(2)=2.3\times(2)^3+0.01\times(2)^2 \\ h(2)=18.4+0.04 \\ h(2)=18.44 \end{gathered}[/tex]
