While playing catch with a friend, Alvin tosses a ball into the air. Its distance above the ground in feet, f(x), depends on the number of seconds, x, since the ball left Alvin's hand.

What does f(0) = f(3) tell you?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
