By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.
That gives us point (3,5) as the top of the parabola. So there you go, answer A.
Answer:
slope is 2. y-intercept is (0,5)
Step-by-step explanation:
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. y = mx + b. Find the values of m and b using the form y = mx + b.
