F(0, -4)
An equation of the parabola is:
a) y = -x^2 + 4
b) y = x^2 + 4
c) y = x^2 - 4
d) y = -x^2 - 4

Answer 1

The equation of the parabola is y = ax + bx².

Step-by-step explanation:

The equation of a parabola can be written in the form y = ax + bx². To obtain this expression for the trajectory of a projectile, we can solve the equation x = Voxt for t and substitute it into the expression for y = Voyt - (1/2)gt², where Vo is the initial velocity, g is the acceleration due to gravity, and t is the time. After substituting and simplifying, we obtain an equation of the form y = ax + bx², where a and b are constants. So, the correct equation of the parabola is y = ax + bx².
