Answer:
x ≤ 15
Step-by-step explanation:
25x + 225 ≤ 600
Subtract 225 from both sides and get
25x ≤ 375
Divide 25 from both sides and you´ll get
x ≤ 15
Answer:
all real numbers
the domain of any parabola is all real numbers because it gets wider.
Answer: Yes. (gof)(0) = -5
(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)
We know f(0) is -1, so we can plug -1 into the equation of g(x)
(gof)(0) = (-1) - 4
(gof)(0) = -5
