Which of the following is the function representing the graph below? f(x)=4^x f(x)=4^x-3 f(x)=4^x+3 f(x)=4^(x+3)

Hence, the function representing in the graph is:

Step-by-step explanation:

Clearly after looking at the given graph of a function we could observe that:

when x= -3 the function takes the value as  F(-3)=1

Hence, we will check in each of the options:

A)

when x= -3 we have:

Hence, option: 1 is incorrect.

B)

when x= -3 , we get:

Hence, option: B is incorrect.

C)

when x= -3 , we get:

Hence, option: C is incorrect.

D)

when x= -3 , we get:

                         Hence, option: D is correct.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
