The distance traveled by a falling rock is modeled d= 5t squared, where d is the distance in meters and t is the time in seconds. Write and simplify an expression for the distance the rock falls in 2t seconds.

the forst and 3rd

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
