John is standing on a bridge when he accidentally drops his toy over the railing. The table shows the height in feet, f(t), of the toy at t seconds.

Choose the function that represents the data.

f(x) = −x16 + 200
f(x) = −16x2 + 200
f(x) = −16x + 200

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

the answer is 8.64

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
