Question 1044567: Much appreciated for any help!
sketch the graph of the following parabolas. The graph should contain the vertex, the y-intercept, x-intercepts (if any) and at least one point on either side of the vertex

A) f(x)=3(x-1)^2+12
B) f(x)=X^2-16x+55
C) f(x)=x^2-2x+5

Only doing (B) for you.

Vertex is (8,-9). This is readable directly from the standard form equation.

The x-axis intercepts?

y-axis intercept?
Look again at the GENERAL FORM equation. (0,55) is the vertical axis intercept.
