the diagram below shows two points, A and B that are 3 cm apart, Around each points are 6 circles of radius 0.5cm, 1cm, 1.5cm, 2cm, 2,5 cm and 3cm. Each has either A or B at its centre On the diagram mark with a cross any point that are 2.5cm away from A and 2.5cm away from B

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
