Jose answered 9 out of 10 correct on a test write his score as a percent

The answer is 90%. All you have to do is convert the fraction, 9/10, to a percent, 90%. You can even convert it to a decimal, 0.9.

Hope this helps! :D

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

good luck on ur quiz test or homework. have a good day : )
