Question

Which graph represents exponential decay? On a coordinate plane, a straight line has a negative slope. On a coordinate plane, a graph starts at (negative 2, 0) and curves up and to the right into quadrant 1. On a coordinate plane, a graph approaches y = 0 in quadrant 1 and curves up into quadrant 2. On a coordinate plane, a graph approaches y = 0 in quadrant 2 and curves up into quadrant 1.

Answer 1

Answer:

Its graph C.

Step-by-step explanation:

I just took the test

Answer 2

Answer:

The correct option is (C).

Step-by-step explanation:

The exponential function representing decay is as follows:

$y=y_{0}\cdot e^{kt};\ k$

Here,

y = final value  

y₀ = initial value  

k = growth rate  

t = time passed

The graph represents exponential decay is:

"On a coordinate plane, a graph approaches y = 0 in quadrant 1 and curves up into quadrant 2."

Thus, the correct option is (C).
