Draw a histogram for the intervals 12-14, 15-17, 18-20 and 21-23 using the following data: 15, 15, 20, 15, 21, 2018, 13, 20,
17,22, 16, 17, 15, 14, 15, 23, 15, 12, 16

really your just stupid if you don't know this

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

um is there supposed to be a picture?
