Answer:
The answer is Tonya's phone had the greater initial trade-in value.
Leo's phone decreases at an average rate slower than the trade in value of Tonya's phone.
Step-by-step explanation:
Given
Tonya

Leo




Solving (a): The phone with greater initial value
The initial value is when x = 0. So, we have:




From Leo's table

By comparison;

i.e.

<em>So: Tonya's had the greater initial trade-in value</em>
Solving (b): The phone with lesser rate
An exponential function is:

Where:

For Tonya

For Leo, we have:


So, the equation becomes:

and 
Solving
, we have:



becomes

Divide both sides by 480

Take square roots

-- Leo's rate
By comparison; Leo's rate is slower i.e. 0.87 < 0.88
Greater than is the answer
Answer:
The Green Monster is a popular nickname for the 37-foot-2-inch-high (11.33 m) left field wall at Fenway Park, home to the Boston Red Sox baseball team. The wall is 310 feet (94 m) from home plate and is a popular target for right-handed hitters.
Step-by-step explanation:
Answer with Step-by-step explanation:
We are given function

a.From given we can see that
When x approaches to infinity then y also approaches infinity.
When x approaches-infinity then y also approaches infinity.
b.To find the x-intercept
Substitute y=0



x=2


x-intercept:(0,0),(2,0),(-2,0)
To find the y-intercept
Substitute x=0

y-intercept:(0,0)
The slope of the line is rather negative 15 not positive 15 while the y-intercept is 20.
