Suppose f(x)=x^2 and g(x)=(1/3x)^2 which statement comepare the graph of f(x) to the graph of g(x)

a. the graph of g(x) is the graph of f(x) horizontally compressed by a factor of 3
b. the graph of g(x) is the graph of f(x) shifted up (1/3) units right
c. the graph of g(x) is the graph of f(x) vertically stretched by a factor of 3
d. the graph of g(x) is the graph of f(x) horizontally stretched by a factor of 3

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
