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.
<span> 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.</span>
