1) identify the end behavior of the function ƒ(x) = −7x3 + 7x2 + 5x − 2. a) ƒ(x) → +∞, as x → −∞ ƒ(x) → +∞, as x → +∞ b) ƒ(x) → −∞, as x → −∞ ƒ(x) → −∞, as x → +∞ c) ƒ(x) → −∞, as x → −∞ ƒ(x) → +∞, as x → +∞ d) ƒ(x) → +∞, as x → −∞ ƒ(x) → −∞, as x → +∞

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

the answer is simply just 6n add the two together as they have an n

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
