I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
The domain is (-infinity, 6] I believe.
Answer:
3.1
Step-by-step explanation:
19.9 = 9y - 8
+8 +8
27.9= 9y
/9 /9
3.1 = y
Check:
9(3.1) - 8 =
27.9 - 8 = 19.9
Answer:
f(x) is reflected over the x-axis and vertically scaled by a factor of 3
Step-by-step explanation:
If you compare the two functions, you see that ...
g(x) = -3f(x)
Multiplication by -1 effects a reflection over the x-axis. (All y-values are transformed to their opposite.)
Multiplication by 3 is a vertical scaling by a factor of 3.
Taken together, f(x) is reflected over the x-axis and vertically scaled by a factor of 3.
Answer:
