# How to find the y-intercept given f(x) = -3x^2 + 6x -2?

$\text{y-intercept } = - 2$
$\text{The graph crosses the y-axis when x = 0}$
$\text{substituting x = 0 into the equation gives the y-intercept}$
$\Rightarrow f \left(0\right) = 0 + 0 - 2 = - 2 \leftarrow \textcolor{red}{\text{y-intercept}}$
