Answer:
D
Step-by-step explanation:
To shift down:
F(x)-b
To shift up:
F(x)+b
To shift right:
F(x-b)
To shift left:
F(x+b)
The answer to the question is x > 4
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
Answer:
-0.008
Step-by-step explanation:
Hi there,
When you have a negative exponent, it tells us how many times to multiply the reciprocal of the base. For example, this problem tells us to multiply the reciprocal of -5 (which is -
) three times since the exponent is -3. As a final solution, you should get -0.008.
Hope this explanation helps. Cheers.
