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 xintercept? What do the xintercepts of the graphs of f(t) and g(t) represent? (4 points)

Best ResponseYou've already chosen the best response.0Part C: Determine the yintercepts of both functions and explain what this means in the context of the problem. Ionly need help with part C

Best ResponseYou've already chosen the best response.1ok, it's asking for the yintercepts, so we set t = 0 and find f(t) and g(t) when t = 0, what does f(t) = ?

Best ResponseYou've already chosen the best response.1next step: t = 0 26t = ?

Best ResponseYou've already chosen the best response.1good. so f(t) = 0 when t = 0 that means the yintercept of f(t) is 0

Best ResponseYou've already chosen the best response.1now, are you ready to find the yintercept of g(t)?

Best ResponseYou've already chosen the best response.0I think i get lost when you said f(t)= 0 when t = 0?

Best ResponseYou've already chosen the best response.1ok, we are given the function f(t) = 16t2 + 26t to find the yintercept, we must find the value of f(t) when t = 0, is that clear?

Best ResponseYou've already chosen the best response.0so we replace the ts with zeros?

Best ResponseYou've already chosen the best response.1so, when t = 0 f(t) = 16t^2 + 26t = 16(0^2) + 26(0) = 0, is that clear?

Best ResponseYou've already chosen the best response.0so f(t)16(0)^2+26(0)?

Vocaloid

Best ResponseYou've already chosen the best response.1right, and we calculate that out f(t)=16(0)^2+26(0) = 0

Best ResponseYou've already chosen the best response.0the y intercept is out equation?

Vocaloid

Best ResponseYou've already chosen the best response.1the yintercept is a number, and to find that number, we find f(t) when t = 0

Best ResponseYou've already chosen the best response.1look at the table again look at the row where t = 0 what number is on the right hand side?

Vocaloid

Best ResponseYou've already chosen the best response.1good, so the yintercept of g(t) is 0

Best ResponseYou've already chosen the best response.1ok, it also asks you to explain what the yintercepts mean in the context of the problem we know that t represents time, so when t = 0, time = 0 seconds f(t) represents the height of the labrador, and g(t) represents the height of the foxhound since both yintercepts are 0, that means that both dogs start off at a height of 0
