The equation y=4.74× + 20 gives the cost y of towing a car if the car is towed x miles. according to the model what ishe the best estimate of the cost for towing a car 22 miles

step-by-step explanation:

; fx

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
