Answer:
07
Step-by-step explanation:
3z - 7 = 14
3•7=21
21 - 7 = 14
Answer:
the numbers are -20 and 5
Step-by-step explanation:
(f o g)(-3) = (f(g(-3))
Because g is on the inside, we carry out g first.
g(x) = x^2 - 3
Substitute -3 in for x.
g(-3) = (-3)^2 - 3 = 9 - 3 = 6
g(-3) = 6
Next, carry out f on the result of g(-3)
f(6) = 2(6) - 1
= 12 - 1
= 11
So the answer is 11.
