Question

Evaluate the function f(x) at the given numbers (correct to six decimal places). f(x) = x2 − 9x x2 − 8x − 9 , x = 0, −0.5, −0.9, −0.95, −0.99, −0.999, −2, −1.5, −1.1, −1.01, −1.001

Answer 1

Answer:

See the attachment. (All results are integers, so are correct to 6 decimal places.)

Step-by-step explanation:

The function simplifies to ...

... f(x) = x(x-9)/((x+1)(x-9))

... f(x) = x/(x+1) . . . for x ≠ 9
