What is the domain of the function f(x) = 2x + 5?
o a.
all real numbers except 2
o b. all real numbers
o c. all real numbers except 5
od. all positive real numbers

There is no value that x cannot be for linear equations.

Thus, the domain is ALL REAL NUMBERS.

CHOICE B.

"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.

you need to give us more information since we can't answer
