Answer:
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.
Answer:
7x^3 - 7x^2 + 35x
Step-by-step explanation:
7x(x^2-x+5)
7x^3-7x^2+35x
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
Answer:
well... this normal addition
Step-by-step explanation:
9+8=17
9+1=10
5+4=9
5+2=7
3+4=7
3+1=4
Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:
__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0
Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.
