Guys help me please my sister needs help

(8 + 3) x ( 7 – 8)

priority 1st for the equation inside brackets

so 11+-1

=10

solve for the ones in the brackets

(8+3) = (11)

(7-8) = (-1)

(11) x (-1)

11 x (-1)

answer = -11

i can't see the picture : /

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
