Question

HELP! MEDAL AND FAN!
Compare and contrast the process for graphing a linear function with the process for graphing a quadratic function.

Answer 1

Ax+By=C
x-intercept plug in 0 for y and solve for x
y-intercept plug in 0 for x and solve for y
y=ax^2+bx+c
if a=+ upwards-->minimum point
if a=- downwards-->maximum point
vertex=(h,k) h=-b/2a h or k may either represent the vertex or the center of graph
k=f(h) plug h into your equation
axis of symmetry x=h
