Answer:
(B) Is the answer here
Step-by-step explanation:
Well a function’s domain can’t repeat no matter what.
Domain is X.
So the first one doesnt work since it repeats to every single digit that exists.
The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.
Answer:
37
Step-by-step explanation:
To find the answer to this equation, we need to substitute 5 into where x is in the original equation.
f(x) = 8x-3
f(5) = 8(5)-3
f(5)= 40-3
f(5)= 37
and that's it! no further simplifying.
(1) k = a + b
(2) a + b + k = 30
subtitute a + b = k to (2)
k + k = 30
2k = 30 |divide both sides by 2
k = 15
