20 points algebra problem ( I solved it need to double check) A manufacturer makes circular targets that have an area of 15ft^2 According to competition rules the area in error can be in no more than .5 ft^2 Use absolute inequality to find the acceptable range of values for the radius.

I solved this problem just need to double check it

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

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
