Question

Which of the following does not represent a function?

graph of an absolute value function
graph of a negative parabola oriented about the y axis with y intercept at positive 6
graph of an ellipse with y intercepts negative 7 and positive 7
graph of a line with a positive slope and y intercept of negative 6

Answer 1

these are the graphs i think it is a

Answer 2

graph of an ellipse with y intercepts negative 7 and positive 7 because for x value several y alues correspond which is no a function

Answer 3

i believe this is a also :)

Arnold deposited some money in a bank. The bank paid him a simple interest every year. After t years, the amount of money f(t), in dollars, that the bank paid Arnold was $1,000 more than 20 times the number of years. Which statement best describes the steps to sketch a graph showing the relationship between f(t) and t?

Label t on the x-axis and f(t) on the y-axis, and plot a graph having slope = 20 and y-intercept = 1000.
Label t on the x-axis and f(t) on the y-axis, and plot a graph having slope = 1000 and y-intercept = 20.
Label f(t) on the x-axis and t on the y-axis, and plot a graph having slope = 20 and y-intercept = 50.
Label f(t) on the x-axis and t on the y-axis, and plot a graph having slope = 1000 and y-intercept = 50.
