now, to get the y-intercept, we simply set x = 0 and solve for y, and to get the x-intercept, we set y = 0 and solve for x.

Concert 2/5 into a percent 5*20 = 100 (denominator) so 2* 20 =40
40/100 is 40%
I'm guessing you accidentally put the dor in front of 52 so it would be 40 at least and 52.57 at greatest
If your quadratic function has x intercepts of 4 and -3, that means that the points are (4, 0) and (-3,0), or the values x has when y=0. Since your quadratic (which represents y) must then equal 0, then your factors of that equation would potentially equal 0 as well. That means that if x=4, then subtract 4 from each side to get x-4=0, and so one factor is (x-4) Similarly your other factor would be (x+3).

<span>(x-4)(x+3)=0 </span>
<span>x^2-x-12=0</span>
