¿Cuál de las siguientes relaciones no es función? * 1 punto
A) {(-1,8), (8,0), (1,8)}
B) {(-1,2), (-2,3), (-4,5), (-5,5)}
C) {(5,6), (0,8), (-3, 10)}
D) {(0,2), (1,3), (0,4), (3,5)}

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

50x5=$250

step-by-step explanation:

total of apples - take away four

6-4 = 2

answer is 2 apples

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
