Mr. Chen is parking in a lot downtown. The graph shows the relationship between the time and total cost of parking. Evaluate the function for an input of 10

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

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
