Question

The function is defined by f(x) = x ^ 2 + 3 . Find f(4y) .

Answer 1

Step-by-step explanation:

The question is given below as

`\begin{gathered} f(x)=x^2+3 \\ find, \\ f(4y) \end{gathered}`

Concept:

Substitute the value of x with 4y in the function above, we will have

`\begin{gathered} f(x)=x^(2)+3 \\ f(4y)=(4y)^2+3 \\ f(4y)=16y^2+3 \end{gathered}`

Hence,

The final answer is

`\Rightarrow f(4y)=16y^2+3`
