How do you write #f(x)= -x^2 + 3x + 10# in vertex form and identify the vertex, y intercept and x intercept?
x-cordinate of vertex:
y-coordinate of vertex:
To find y-intercept, make x = 0 --> y = 10
To find x-intercepts, solve f(x) = 0.
Find 2 numbers knowing sum (-3) and product (-10).
The 2 real roots (x-intercepts) are: -2 and 5.
