Answer:

(x + 1)(x - 1) (x- 2)(x - 5)

Step-by-step explanation:

<u>Solving in steps:</u>

x^4 - 7x^3 + 9x² + 7 x – 10=
(x^4 - 1 )- (7x^3 - 7x) + (9x^2 - 9) =
(x^2 + 1)(x^2 - 1) - 7x(x^2 - 1) + 9(x^2 - 1) =
(x^2-1)(x^2 + 1 - 7x + 9) =
(x + 1)(x - 1)(x^2 - 7x + 10) =
(x + 1)(x - 1)((x^2 - 2x) - (5x - 10)) =
(x + 1)(x - 1) (x- 2)(x - 5)

Which function could be a stretch of the exponential decay function shown on the graph?

Ainat [17]

The function that could be a stretch of the exponential decay function shown on the graph is B. f(x) = One-half(6)x.

<h3>How to illustrate the function?</h3>

From the information given, it can be seen that function A is a monotonically increasing function.

Also, it can be seen that C and D don't pass through (0, 1).

Therefore, the function could be a stretch of the exponential decay function shown on the graph is B.
