--------------
Since the product is 0, either 5x = 0, or (2x-3) = 0
5x = 0
x = 0
---------
2x-3 = 0
2x = 3
x = 3/2

Given: ---> ,--> where

Solving for the X-Intercepts:
Disciminant:
Then, by Quadratic,

X-Intercepts, (1.5,0) & (0,0)

Let fx=0 ---->

Y-Intercept, (0,0)

For the vertex:
For Y, subst. x= 3/4 to the eqn:

The vertex, (3/4, -5.625)
We'll see the graph:

Thank you,
