The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation:
f(t) = 6 + 30t – 16t²
Where f(t) is the height of the football after t seconds.
The constant 6 means the football was thrown from a height of 6 feet above the ground.
The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.
