Best ResponseYou've already chosen the best response.0An Labrador leaps over a hurdle. The function f(t) represents the height of the Labrador above the ground, in inches, at t seconds: f(t) = 16t2 + 26t A foxhound jumps over the same hurdle. The table shows the height of the foxhound above the ground g(t), in inches, at t seconds: Time (t) g(t) 0 0 0.4 5.44 0.6 6.24 0.7 6.16 0.8 5.76 1.0 4 1.2 0 Part A: Compare and interpret the maximum of f(t) and g(t)? (4 points) Part B: Which function has a greater xintercept? What do the xintercepts of the graphs of f(t) and g(t) represent? (4 points) Part C: Determine the yintercepts of both functions and explain what this means in the context of the problem. (2 points)

Best ResponseYou've already chosen the best response.0think you will agree that the "maximum" of \(f(t)\) is \(6.24\) right?

Best ResponseYou've already chosen the best response.0\[f(t) = 16t^2 + 26t\] maximum is where \(t=\frac{26}{2\times(16)}=\frac{13}{16}\) we gotta plug that in

Best ResponseYou've already chosen the best response.0oh no i made a mistake the maximum of \(g\) is \(6.24\) not of \(f\) the maximum of \(f\) is \(\frac{169}{16}=10.5625\) so \(f\) gets bigger than \(g\)

Best ResponseYou've already chosen the best response.0Part a) the max of g(t) occurs when t=0.6 seconds, for f(t) since the parabola is concave down due to the negative sign then we know that there is a max on the parabola, the max for f(t) occurs at (13/16,169/16) 169/6=10.5625inches at time 0.8125seconds Part b) f(t) has greater x intercepts, meaning that when the labrador will land later than the fox when it jumps over the hurdle lol
