Step-by-step explanation:
y=4x^2-7
vertex(0,-7)
Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".
Answer:
13. Answer: 0
17. Answer: 3
19. Answer: 2
Step-by-step explanation:
13. f(g(3))
First find g(3) on the right graph.
We see that at x = 3, g(x) = 4
So g(3) = 4
Next find f(g(3)). Since g(3) = 4, that means we have to find f(4) and the from the left graph we see that f(4) = 0 answer
17.f(f(5))
f(5) = 1
f(f(5)) = f(1) = 3 answer
19. g(g(2))
g(2) = 0
g(g(2)) = g(0) = 2 answer
A c and d are the answers
