Find the domain and range of the relation and determine whether it is a function.

a. domain: all real numbers; range: all real numbers; yes, it is a function.
b. domain: positive integers; range: positive integers; no, it is not a function.
c. domain: x ≥ 0; range: y > 3; no, it is not a function.
d. domain: x > 3; range: y > 0; yes, it is a function.

Find the y-intercept and x-intercept for the equation 5x-3y=60 what is the y-intercept

Suppose that one doll house uses the 1 inch scale, meaning that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. if the doll house is 108 inches wide, what is the width of the full-sized house that it's modeled after? in inches and feet.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
