Answer:

The domain of f is {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

Step-by-step explanation:

The domain of a function is all the values of x make the function defined

In the given graph

∵ The graph drawn from x = -7 to x = 7 and from y = -6 to y = 4

→ That means the values of x started from -7 and ended at x = 7

∵ The coordinates of the starting point of the graph of f are (-7, -5)

∵ The coordinates of the ending point of the graph of f are (7, 3)

∴ -7 ≤ x ≤ 7

∵ Values of x are the domain of the function

∴ The domain of the function is -7 ≤ x ≤ 7

∴ The domain of f = {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

Answer:

Student 2 is incorrect because he didn't use the formula properly

Step-by-step explanation:

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

$C(3)=\$1000\cdot(1-0.4)^3$

$C(3)=\$1000\cdot0.6^3$

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly
