Question

sketch the graph of the following function:
p(x)= 4x^2-20x+25
can help me sketch the graph?

Answer 1

Okay, this is easy, the lowest point of this parabola will be x=5/2 and y = 0, then we find the y, when x=0 and the x, when y=0,

{x=0, y=25} {y=0, x=5/2)

Answer 2

just calulate some points to make it easier to draw, er go, put x=1, x=2 x=-1 in the equation and plot the points

Answer 3

if you know MATLAB programe you can calculete the x=? x=? somethınk lıke that and you draw skecth graph.
