Analyze h(x)

Given h(x) = (-32x^2)/(130)^2, do A to C.

A. Find x when h(x) = 0.

The set up us this:


0 = (-32x^2)/(130)^2


You say?


B. Find domain of h algebraically


To find domain, I must repeat my work for part A.


You say?


C. Find range of h algebraically


How is this done algebraically?



D. Find all intercepts


To find the x-intercept(s), I must let h(x) = 0.


Yes?


To find the y-,intercept(s), I must let x = 0.


Yes?


What do you really say?

Re: Analyze h(x)

A ok.

Have a look at the graph for the rest.

I will use a graph.

Ok?!
I see him just replacing h(x) with a zero:
0 = (-32x^2)/(130)^2

I guess he needs to go on a bit further to deduce the value of x.

I expected to read instead:

Both correct.

Perfect. I can take it from here.
