Which function represents exponential decay with 5% as the rate of decrease?

The function that represents exponential decay is y = 50 ⇒ B

Step-by-step explanation:

The form of the exponential growth function is y = a

The form of the exponential decay function is y = a

∵ The function represents exponential decay with 5%

→ By using the second rule above

∴ y = a

∵ The rate of decrease is 5%

∴ r = 5%

→ Change it to decimal by dividing it by 100

∵ 5% = 5 ÷ 100 = 0.05

∴ r = 0.05

→ Substitute it in the equation

∵ y = a

∴ y = a

→ Look at the answer to find which equation is written in this form

∴ y = 50

∴ The function that represents exponential decay is y = 50

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
