Question 437124
Make a graph of y=6x^2-4x-3 and find the vertex, y-intercept, extra points.
-----------
For the y-intercept, set x = 0
--> y = -3, or (0,-3)
----------------
For the vertex, find the line of symmetry
It's x = -b/2a
x = -(-4)/(2*6) = 1/3
The vertex is (1/3,f(1/3))
Sub 1/3 for x
--> 6*(1/9) - 4/3 - 3
= - 11/3
Vertex at (1/3,-11/3)
---------------
For "extra points", pick values for x and find y
x = 1, y = -1 --> (1,-1)
x = 2, y = 13 --> (2,13) etc
