How do find the y-intercept of $y = 1 - e^{x}$ $y = 1 - e^x$ ?

1 Answer

The y-intercept of $y = 1 - e^{x}$ $y=1-e^x$ is 0

Explanation:

The y-intercept is the value of $y$ $y$ when $x = 0$ $x=0$

${(anything)}^{0} = 1$ $("anything")^0 = 1$
$\Rightarrow e^{0} = 1$ $rArr e^0 = 1$

So when $x = 0$ $x=0$
$XXXX$ $color(white)("XXXX")$ $y = 1 - e^{0} = 1 - 1 = 0$ $y = 1 -e^0 = 1-1 = 0$
