Me asap? will mark brainliest to the best answer : )) the table below shows the squares of different numbers: number (x) 2 −2 3 −3 square of the number (y) 4 4 9 9 part a: does the table represent y as a function of x? justify your answer. part b: the total cost f(x), in dollars, for renting a rowboat for x hours is shown below: f(x) = 20 + 3x what is the value of f(150), and what does f(150) represent?

Part A: Does the table represent y as a function of x? Justify your answer.

Yes, this table does represent y as a function of x. No x-value appears more than once, and in each case, there is exactly ONE associated y-value. Were there more than one associated y-value, the table would not represent a function.

f(x) = 20 + 3x

What is the value of f(150), and what does f(150) represent?

Substitute 150 for x (in two instances) in the given function:

f(150) = 20 + 3(150) = 20 + 450 = 470. This is the value of the function when the input value (x) is 150 units.

f(150) is functional notation represents the value (y-value) of the function when the input (x-value) is 150 units.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
