Question

Find a quadratic function f(x)=ax^2+bx+c

Answer 1

y-intercept 2; x=intercepts 1 and 5

Answer 2

did you know that x-intercept is the value of x when y = 0?

Answer 3

I know nothing, I just started learning this and I'm so lost on homework. But yes, I do know that :P @lgbasallote

Answer 4

im gonna tell you one more thing...the x intercepts of a quadratic function are also the roots of the function

Answer 5

at x=0 from y-intercept you will have c=2
then you will have equations
first at x=1
a+b+2=0
second at x=5
25a+5b+2=0
then you can solve for a and b

Answer 6

So the point is to find a and b? @El-naggar

Answer 7

@sakigirl yes to know the form of the quadratic function you must know a,b and c
