An expression is shown below:

f(x) = -16x^2 + 24x + 16
What are the x - intercepts of the graph?
How can you tell if a vertex is a maximum or a minimum?

nnesha · Answer

x -intercepts   = solutions = zeros or what you wanna call it 
x-intercepts when  graph of quadratic equation  cross x-intercept , when y =0
so replace y by zero and solve for x by applying quadratic formula

Lets see....I think it is (2,0) and (-0.5,0)

vertex 
you can find out that by looking at the equation  |dw:1429128436850:dw|
