Part 1: Multiple Choice
1.
Determine the y-intercept:
f(x) = x3 – 5x2 – 25x + 125
O (0,0)
(0.25)
(0.125)
(0.5)

Option C: (0,125) is the y - intercept.

Explanation:

The given function is

We need to determine the y - intercept.

The value of y - intercept:

The y - intercept is the value of y when x = 0

The y - intercept of the function can be determined by substituting x = 0 in the function.

Hence, let us substitute x = 0 in the function , we have,

Simplifying the terms, we get;

Thus, the value of y is 125.

Hence, the y - intercept is 125.

Therefore, the coordinates of the y - intercept are (0,125)

Hence, Option C is the correct answer.

the answer is ! ?
