The other x-intercept is:
(1/2, 0) OR (.5, 0)
40%
Because, 2/5 equals 4/10. 10x10=100, so 4x10=40, so 40%.
350(1+0.75)t (add the numbers)
350*1.75t (Calculate the product)
612.5 t
Evaluate the function at the three values of the range and see what you get. The appropriate choice is ...
... D) {15, 3, 0}
_____
Evaluation can sometimes be simpler if you rearrange the function to a form called "Horner's form."
... f(x) = (x -4)x +3
Then the evaluation looks like (for x=-2) ...
... f(-2) = (-2-4)(-2)+3 = (-6)(-2) +3 = 12 +3 = 15
This is sufficient to identify D as the answer of choice.
The answer is D. ..........
