Question

Which of these statements is true?

Answer 1

any thoughts so far? the important thing to remember is that the x-coordinate represents time and the y-coordinate represents height

Answer 2

the answer is C

Answer 3

hm, that's not quite right, see how the y-intercept is (0,5) not (0,0)? that means the projectile was launched from a height of 5 not the ground

Answer 4

ok the projectile was launced from a height of 5 C is not

Answer 5

hint - how long does it take to reach the vertex? (the maximum)

Answer 6

first correct me if i'm wrong, it's increasing

Answer 7

it's increasing, but how long does it take to reach the top? (hint: what's the x-coordinate of the vertex?)

Answer 8

12

Answer 9

good, so the projectile takes 12 seconds to reach the maximum

which answer choice does that lead us to?
