Question
The given equations model the number of teachers and students in a high school from 2002 through 2017. In the equations, n is the number of years after 2002 , where n is a whole number less than or equal to 15 . The predicted number of teachers and students are T (n) and , respectively.
Which of the following is the graph of function ?
The correct answer is:
Given , S(n) = 1,280 + 30 n is of the form slope - intercept form .
We get to know the slope is + 30 (which indicates increasing nature toward +ve x-axis)
We get y -intercept as 1,280 which indicates the graph cuts +ve y axis at + 1,280 .
The Graph in Option A satisfies both the conditions.
