Math Problem Statement
whats the answer
Solution
To determine which statement is true about the y-intercepts of Functions A and B, let's examine each function.
Function A
The graph shows a line crossing the y-axis at . Therefore, the y-intercept of Function A is .
Function B
Function B is given by the equation . This equation is in the slope-intercept form , where represents the y-intercept. In this case, the y-intercept is .
Comparing the Y-Intercepts
- The y-intercept of Function A is .
- The y-intercept of Function B is .
Since , the y-intercept of Function A is greater than the y-intercept of Function B.
Conclusion
The correct statement is: "The y-intercept of Function A is greater than the y-intercept of Function B."
