GRAPHING EXPONENTIAL FUNCTIONS

Mathematics
1 answer:
Brut [27]4 years ago
4 0
<span>1. If (-1, y) lies on the graph of y = 3^(x+1), then y = 3^(-1 + 1) = 3^0 = 1

2. If (x, 1/100) lies on the graph of y = 10^x, then 1/100 = 10^x
10^-2 = 10^x
x = -2

3. If (-1, y) lies on the graph of y = 2^2x, then y = 2^2(-1) = 2^(-2) = 1/4

4. The relationship between the graphs of y = 2^x and y = 2^-x is reflections over the y-axis.

5. If (3, y) lies on the graph of y = -(2x), then y = -2(3) = -6

6. All are not exponential

7. If (-2, y) lies on the graph of y = 4^x, then y = 4^(-2) = 1/4^2 = 1/16

8. If (-3, y) lies on the graph of y = 3^-x, then y = 3^-(-3) = 3^3 = 27

9. If (-3, y) lies on the graph of y = 3^x, then y = 3^(-3) = 1/3^3 = 1/27

10. If (-3, y) lies on the graph of y = (1/2)^x, then y = (1/2)^(-3) = 2^3 = 8</span>

Helpppppp me with question 4 Thursday pleaseeeeeeeeeeeeeeee
Gennadij [26K]
If x is 0 then I think it would be the 3 to the second power and that is 9. Because 0 + 9 = 9. Correct me if I’m wrong!

Mr.sanchez drives 120 miles in 3 hours. At the same rate, how far will he drive in 5 hours
Rina8888 [55]
To elaborate:

To do this problem, we assume that Mr. Sanchez is driving at a constant rate.

According to this information, he has driven 120 mi in 3 hr. To find how much he drives in 5 hr, we first have to find how many mi he drives in 1 hour. To do this, we divide 120 miles by 3 hours, since we assume that he managed to drive an equal amount in each hour.

120/3=40

Therefore Mr. Sanchez drove at a rate of 40 mph.

However, this isn't the final answer. 40 miles is the distance for one hour of driving. To find the distance for 5 hours, we have to multiply the distance by 5 as well.

40 times 5=200

In conclusion, Mr. Sanchez will drive 200 miles in 5 hours.
