Sanjay graphs a quadratic function that has x-intercepts of -3 and 7. Which functions could he have graphed? Check all that apply.
9(1) = 12
• 4x-21
U 9(1) = (x - 3)(x + 7)
(1) = 312 - 12x - 63
9(1) = -(x + 3)(x - 7)
g(x) = 12 + 4x - 21

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
