quadratic function/inequality, multi-step problem and I am stuck
Hi everyone, happy Tuesday!
I am taking algebra and I just don't get quadratics. I have a sheet of different quadratic questions I have been working on since yesterday, trying to figure it out before coming here, but I failed :(
I have a couple questions below, thank you in advance for your help :)
a. determine if it goes up or down..... down I got that far :)
b. find the vertex, this is where I got stuck
c. find axis of symmetry
d. find x- and y- intercepts
e. sketch the graph y=f(x)
f. determine whether the function has a maximum value or a minimum value, then find this value (What, I am so lost!)
g. find the range of f.
ahh why are there so many questions for one function!
3.) I am stuck on this one because the fractions killed me, er
solve the quadratic inequality:
1/2x^2 - 3/4x + 7 <(or equal, didn't know how to add the bar under) 0
