PLEASE HELP ASAP!! A teenager who is 5 feet tall throws an object into the air. The quadratic function f(x) = -16x^2 + 64x + 5 is where f(x) is the height of the object in feet and x is the time in seconds.
Which function is equivalent to the given function?
f(x) = -16 (x - 2)^2 - 59
f(x) = -16 (x - 2)^2 - 11
f(x) = -16 (x - 2)^2 - 5
f(x) = -16 (x - 2)^2 + 69

differnt varibles efect the range

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
