Question

Let f(x)=x^2+3. Find F(2)

Answer 1

7

Explanation:

When you put a value for x in a function, it means that you substitute all terms of x for that value you just substitute for x=2. The x term in the function is x^2, so that squared would be 4. You then add 3, yielding a total result of 7.

Answer 2

f(2) = 7

Step-by-step:

Solution :

Let f(x)=x^2+3. Find f(2)

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

`\begin{gathered}{\longrightarrow{f(2)= {(2)}^(2) +3}}\end{gathered}`

`\begin{gathered}{\longrightarrow{f(2)= {(2 * 2)}+3}}\end{gathered}`

`\begin{gathered}{\longrightarrow{f(2)= {(4)}+3}}\end{gathered}`

`\begin{gathered}{\longrightarrow{f(2)= 4+3}}\end{gathered}`

`\begin{gathered}{\longrightarrow{\underline{\underline{f(2)= 7}}}}\end{gathered}`

Hence, the value of f(2) is 7.
