1. ### Does the "k" and "c" in these quadratics equal the y intercept? y= a(x-p)^2 +q and y=ax^2 +bx =+c

In the first one you need to evaluate the equation for x = 0 to find the y-intercept. y = a(0-p)^2 + q y = ap^2 + q this will be the y -intercept You can do the same in the second, but it will be "c", yes.
