Answer:
The y intercept is -21
Step-by-step explanation:
y = (x - 3)(x + 7)
To find the y intercept, set x =0 and solve for y
y = (0-3) (x+7)
y = -3*7
y = -21
The y intercept is -21
10 times 0.84 is 8.4 or 8.40 is completely fine as well.
The maximum height of the diver would be the y value of the vertex of the graph. The vertex of the graph is (1,4). The maximum height of the diver is 4 meters.
The answer would be B 11 yards 1 foot
