Which of the following describes the end behavior of the function ƒ(x) = x4 + 3x3 – 2x + 7? Question 20 options:

A)

As x → –∞, y → –∞ and as x → +∞, y → +∞

B)

As x → –∞, y → –∞ and as x → +∞, y → –∞

C)

As x → –∞, y → +∞ and as x → +∞, y → –∞

D)

As x → –∞, y → +∞ and as x → +∞, y → +∞

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

step-by-step explanation:

"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.
