Answer:
Step-by-step explanation:
Given
The attached table
Required
Determine the equation of the table
The table represents an exponential function. So, we make use of
When x = 0, y= 5.
So:
becomes
When x = 1; y = 15
So;
becomes
Substitute 5 for a
Divide both sides by 5
Substitute values for a and b in:
Answer:
y = (1/8)x
Step-by-step explanation:
The relevant basic formula is y = kx, where k is the constant of proportionality.
We must find k. To do this, let y = 15/6 and x = 20 in the above formula:
15/6 = k(20)
We solve for k by dividing both sides by 20: 15/(6*20) = k = 1/8
Then the specific formula for this situation is y = (1/8)x
Answer:
The answer is C. Y= -3x+6
The answer can be found by substitute 0 into x and find the value of y. If the value is same with graph then it is correct.
