Since the ball starts out on the ground before being kicked x=0. find the corresponding value for y, in feet.

Considering an example of football :-

When we kick the ball, it goes through a parabolic path whose equation is given by :-

y = ax² + bx + c

where 'c' is the y-intercept of parabolic curve on coordinate plane.

Depending upon the initial conditions, the value of c varies.

It says the ball starts out on the ground before being kicked, it means y-intercept is on ground i.e. c = 0.

Now the equation would become :- y = ax² + bx.

It says to find corresponding value of y when x=0.

Plugging x=0 in the above equation :-

y = a(0)² + b(0)

y = 0

So, final answer is y = 0.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
