Question

hello ,
can someone please help me how to graph and find the range for this parabola:
f(x) = 2x^2 – 7x + 5

Answer 1

Graph it?
Hmm this one is going to be a little tricky :)
The vertex is located at some fractional points.

Do you remember how to complete the square?
That's what we'll need to do in order to get this into vertex form.

Answer 2

kind of

Answer 3

for a quadratic equation you can complete the square or use

for this form ax^2 +bx + c
find vertex with
-b/2a

Answer 4

plugging -(-7/2(2) =??

once you get that ;ug it back into your equation for x
then you will get the vertex point (x,y)
