Question

Find the y intercept for the parabola defined by this equation: y=-5x^2-11x-2

Answer 1

First, we have to set up the problem like this:
$y=-5\cdot \:0^2-11\cdot \:0-2$
There's a rule that says: $0^a=0$
We are going to use that.
Apply the rule...
$y=-0\cdot \:5-0\cdot \:11-2$
Multiply...
$y=-0-0\cdot \:11-2$
Multiply again...
$y=-0-0-2$
Subtract.
$y=-2$

We have found the y-intercept.
Have a nice day! :)
