Jordan solved the equation −7x + 25 = 48; his work is shown below. identify the error and where it was made. −7x + 25 = 48 step 1: −7x + 25 − 25 = 48 − 25 step 2: −7x = 23 step 3: negative seven times x over seven = twenty-three over seven step 4: x = twenty-three over seven

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)
