If this is algebra, then you will be using a parabola to solve this problem:
t=-b/2a
t=-8/2(-16) = 8/-32 = -1/4
t=-1/4=-0.25
h=-16(0.0625)+8(-0.25)+80
h=1-2+80
h=79
(-0.25,79)
then plug this ordered pair above and draw a line directly down the middle of it to use as a "mirror" and plug 2 different numbers(preferably 0 and 1) into the variable t to find the other two points and then reflect the two points over the "mirror" to get the last two points to graph your paprabola
We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers in interval notation we use a square bracket [ when the set includes the endpoint and a parenthesis ( to include that the endpoint is either not included or the interval is unbounded for example if a person has $100 to spend he or she would need to express the interval that is more than 0 and less than or equal to 100 and write (0, 100]. We will discuss interval notation in greater detail later

To simplify this, use the FOIL method. First, Outer, Inner, Last.
First: Multiply the first numbers in each set of parentheses.
Outer: Multiply the two outermost numbers in the equation.
Inner: Multiply the two innermost numbers in the equation.
Last: Multiply the last numbers in each set of parentheses.
Then, we put them all together in an equation, from the highest exponent to the lowest, then highest prefix (number before the variable) to lowest.
And simplify.
