If f(x) = 3x - 2, find f-'(x)
Answer:
f⁻¹(x) = (x + 2)/3
Step-by-step explanation:
I'm going to assume the question is asking for the inverse. If that is the case, you want to switch x and y in the equation and solve for y.
f(x) = 3x - 2
x = 3f(x) - 2
x + 2 = 3f(x)
(x + 2)/3 = f⁻¹(x)
Therefore, the inverse is f⁻¹(x) = (x + 2)/3.

Step-by-step explanation:
after 4 hours, the water level decreased by 8 feet
which is -8
Therefore -8/4 = -2 change in water level every hour
Answer:
The constant rate of change is 2 feet every hour.
Step-by-step explanation:
Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.
With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2
1 Representing 1 hour
2 Representing 2 feet
Every hour, the water level drops 2 feet.

The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
A numerical distribution with continuous results is a density curve. A density curve is, in other terms, the graph of a continuous distribution. Which implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete).
Also the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is;
P(0≤X≤0.5)
= 1/4 (0.5 - 0)
= 1/4 (0.5)
= 0.125
That is 12.5%
Hence, The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .
