1. The paths of two dolphins playing in the ocean were recorded by some biologists. The first dolphin's path could be modelled by the equation h(t) = 2t4 - 17t³ + 27t² -
252t +232 and the second dolphin's path could be modelled by the equation h(t) =
20t3-200t² + 300t - 200.When was the first dolphin higher than the second dolphin?

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

parallelogram is the   answer
