Question

Please help. If f(x) = 2x² + 3, find f(0). I understand how to solve, but what should my answer look like?

$\huge \boxed{\mathfrak{Question} \downarrow}$

• If f(x) = 2x² + 3, find f(0).

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Given that,

• f (x) = 2x² + 3
• f (0) = ?

To find f (0), we need to substitute 0 in the place of x.

$\sf \: f(x) = 2 {x}^{2} + 3 \\ \longmapsto \sf \: f ( 0 ) = 2 ( 0 ) ^ { 2 } + 3$

Calculate 0 to the power of 2 and get 0.

$\sf \: f(0) = 2\times 0+3$

Multiply 2 and 0 to get 0.

$\sf \: f(0) = 0+3$

Add 0 and 3 to get 3.

$\boxed{ \boxed{ \bf \: f(0) = 3}}$
