h (x) = 2x; find h(4)

Sagot :

Question:

If

[tex]h(x)=2x[/tex]

find

[tex]h(4)[/tex]

The h(4) means that we should replace every value of x in the original function with 4, That is every value of x in the function becomes 4(x=4)

Hence,

Substituting the value of x=4, we will have

[tex]\begin{gathered} h(x)=2x \\ h(4)=2\times4 \\ h(4)=8 \end{gathered}[/tex]

Therefore,

the value of h(4) = 8
