This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.
Your answer is B.
f(x) = 2x²+3 has the same domain and range as x²+3
4>-3
-2>-5
1=1
They want to make sure you understand inequalities and know how to use the inequality signs.
Answer:
(f+g)(x)= 2x²+2x-2
Step-by-step explanation:
-x²+6x-1+3x²-4x-1 can be found by combining like terms.
2x²+2x-2
Answer:
35-7-7-7-7-7=0 also 35-7=28-7=21-7=14-7=7-7=0
Step-by-step explanation:
48-12-12-12-12=0 also 48-12=36-12=24-12=12-12=0
72-8-8-8-8-8-8-8-8-8=0 also 72-8=64-8=56-8=48-8=40-8=32-8=24-8=16-8=8-8=0
