Best Answer

if you make a t chart with the x and y, you can find functions.

the change in y is the number in front of the x (multiplying) and if you find the x at 0, the y will be what you add. here:

y=3x + 1 the 3 is the change in y

the + 1 when you have (0, 1) as a point.

subistite the axis of symmetry into the original problem and solve for y. inentify the vertex
