Answer:
Exponential growth functions are:
Exponential decay functions are:
Step-by-step explanation:
Given:
An exponential function is of the form , where,
.
Now, if a > 0 and b > 1, then the exponential function represent exponential growth.
If a > 0 and 0 < b < 1, then the exponential function represent exponential decay.
Let us check each function now.
Option 1:
Here,
As 1.08 > 1, the function is exponential growth.
Option 2:
Here,
As 0.5 < 1, the function is exponential decay.
Option 3:
Here,
As 0.8 < 1, the function is exponential decay.
Option 4:
Here,
As 3 > 1, the function is exponential growth.
Option 5:
Here,
As 1.07 > 1, the function is exponential growth.
Option 6:
Here,
As 0.93 < 1, the function is exponential decay.
Answer: The y- intercept is -2. The x-intercept is 2/3
The attachment shows the solutions.
Step-by-step explanation: The y-intercept is the "b" term in the slope-intercept form of the equation. To find the x-intercept, substitute 0 for the output and solve for x.
0 = 3x -2 . Add 2 to both sides
2 = 3x . Divide both sides by 3
2/3 = x the x-intercept is 2/3
To find f(-5) substitute -5 for x and solve.
f(-5) = 3(-5) -2
f(-5) = -15 -2
f(-5) = -17
