    An 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 x-intercept? What do the x-intercepts of the graphs of f(t) and g(t) represent? (4 points) Part C: Determine the y-intercepts of both functions and explain what this means in the context of the problem. (2 points)

    think you will agree that the "maximum" of \(f(t)\) is \(6.24\) right?

    \[f(t) = -16t^2 + 26t\] maximum is where \(t=-\frac{26}{2\times(-16)}=\frac{13}{16}\) we gotta plug that in

    oh 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 \(g\)

    y-intercept is when x = 0

    Part 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
