Rory · Answer 1

To find the y-intercept, substitute 0 in for x and solve for f (x) : f (0) = (0) 2 - 3 (0) + 5. Now, let's find the vertex: To findthe x-value of the vertex, use theformula x = - b/2a.

Kaylie Kaufman · Answer 2

There are two easy steps to find the Y intercept:

Step 1:Determine the xvalue of the vertex by finding the average of the zeros. Step 2: Determine the yvalue of the vertex by substituting the xvalue into the original equation and solving for y.
