# What is the y-intercept of the graph of y = 4x^2 + 8x + 3?

May 15, 2018

$\text{y-intercept } = 3$

#### Explanation:

$\text{to find the intercepts, that is where the graph crosses}$
$\text{the x and y axes}$

• " let x = 0, in the equation for y-intercept"

• " let y = 0, in the equation for x-intercepts"

$x = 0 \Rightarrow y = 0 + 0 + 3 = 3 \leftarrow \textcolor{red}{\text{y-intercept}}$
