The domain will be the numbers you can use for x and not get a
undefined thing like division by 0 or square root of a negative number
(f*g)(x)=f(x) times g(x)=(3x+2) times (7x+6)=(3x+2)(7x+6)=
the domain is all real numbers because we can't find any values of x that make a division by 0 or square root of a negative
answer is C
If f = {(-1, 0), (-2, 2), (-3, 4), (-4, 6), (-5, 8)}, what is the range?

Answer:
{0, 2, 4, 6, 8 }
Step-by-step explanation:
the range is the y- coordinates of the ordered pairs , then
range { 0, 2, 4, 6, 8 }
Answer:
Step-by-step explanation:
R=5
T=4.5
D=22.5
5x4.5=22.5
Maybe this is right ? Hope it helps
Kong took
15% fewer seconds than Nolan took. So Kong took
100%−15%=85%
85/.85=.85*?/.85
100=?
Which means that Nolan took 100 seconds.
This is all from Khan Academy so it's correct!!
Hope this helps!!
