What is the range of f(x) = 3x + 9? {yly< 9} {yly> 9} {yly> 3} {yly< 3}

the set of all real numbers

Step-by-step explanation:

f(x) = 3X + 9 is a polynomial, and so both the domain and the range are "the set of all real numbers."  

None of your answer choices match this.  Check with your teacher if you can.

i believe the answer is the polygon, heptagon.

"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.
