Select the correct answer Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function (0) = 45 + 9,
where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x) = 2x +5.
Which function describes the area, A (*), of the porch?
OA. A) = 8x2 + 25 + 45
OB. Aw) = 8x2 +63 + 38
OC. A ) = 8:02 + 45+ 38
D. A) = 8x2 + 387 + 45

Do u just plot the numbers on the graph like (1,

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?

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)
