Use interval notation to represent all values of x satisfying the given conditions. y = 6 - 2(2 - x) and y is at most 18.

a. (-∞, 8)

b. (-∞, 8]

c. (-∞, 9]

d [8, ∞)

Use the graph of the sine function y=2sinθ shown below

Give me the equations of two lines that have the same slope but are not parallel.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
