Let's rewrite the system of equations:
y = three over four times x squared minus 3
y = (3/4) x ^ 2 - 3
y = negative three over four times x squared plus 3
y = (-3/4) x ^ 2 + 3
The system of equations is:
y = (3/4) x ^ 2 - 3
y = (-3/4) x ^ 2 + 3
The solutions are:
(-2, 0)
(2, 0)

This problem can be solved directly by neglecting the
initial velocity given. All we have to do is to plug in t = 4 in the given
equation. That is:
h = -16^2 + 123 * 4
h = 236 ft
Did you mean :
f(x) = x² - 2x, find x = -3
f(-3) = (-3)² - 2(-3)
f(-3) = 9 + 6
f(-3) = 15
