Answer:

The first option is correct.

Step-by-step explanation:

The given function is

f(x)=(\frac{1}{2})^x            .... (1)

The general exponential function is

f(x)=ab^x                         .... (2)

Where, a is initial value and b is the growth factor.

If b>1, then it is a growth function and its graph is an increasing curve.

If b<1, then it is a decay function and its graph is a decreasing curve.

On comparing (1) and (2) we get,

b=\frac{1}{2}

So, f(x) is a decreasing function.

Since f(x) is decreasing function, therefore the graph of the function decreases as the value of x increases. Option 1 is correct.

Jack is a car salesman who works strictly on commission. For every car he sells, he earns a 2% commission. Cars sell for $35,000
Nadya [2.5K]
First we need to find 2% of 35,000

2% equals 0.02 so we'll multiply 35,000 by 0.02

35,000 × 0.02 = 700

for every car he sells jack gets $700

now we need to divide that into 5,000

5,000 ÷ 700 = 7.14

now since you cannot sell 0.14 of a car you need to round up

he needs to sell 8 cars to meet his target income
