When x increases from a to a + 2, y increases by a factor of 16.

for which functions is this statement true?
a) y = 2(4)x
b) y = 4x + 2
c) y = 2(16)x
d) y = 16x + 2

Correct option is A.

Step-by-step explanation:

Given x increases from a to a + 2, y increases by a factor of 16.

we have to find the function for which the above statement is true.

Option A:

⇒

⇒

⇒

⇒

⇒ When x increases from a to a + 2, y increases by a factor of 16.

Hence, option A is correct.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.
