Domain is what you can put in
the domain for most functions is ALL REAL NUMBERs
except for those that violate the dividing by zero thingummy
example
if yu had
f(x)=x+2
domain is all real numbers
f(x)=2/x
domain is all real numbers except for 0 since cannot divide by 0
f(x)=2(x-4)
domain is all real numbers except for 4
so answer is {x|x is a real number}
To remember the ratios, use the mnemonic sohcahtoa.
S = O/H
C = A/H
T = O/A
In this case, we want S, sin. The side opposite angle X would be 24. The hypotenuse is 26, so the ratio is 24/26. <span />
Like radicals are radicals that have the same root number AND radicand (expression under the root).
And there ya have it!
Happy studying.

Answer:
It's B. f(x) = (x + 3(^2 + 1.
Step-by-step explanation:
f(x) ---- > f(x + 3) is a translation of 3 units to the left.
