Explanation Calculation: The given function is n = x 3 − 9 x 2 + 15 x + 600 , where n is the number of monthly crimes and x is the number of the month. It is also given that number monthly crimes is 580. That is, 580 . So, the function becomes 580 = x 3 − 9 x 2 + 15 x + 600 . x 3 − 9 x 2 + 15 x + 600 − 580 = 0 x 3 − 9 x 2 + 15 x + 20 = 0 Solve the equation x 3 − 9 x 2 + 15 x + 20 = 0 . Press the button “ Y = ” to access equation editor Y = and then write Y 1 = X ^ 3 − 9 X ^ 2 + 15 X + 20 . Now, set the viewing window size as follows. X min = − 10 , X max = 10 , and X s c l = 2 Y min = − 10 , Y max = 10 , Y s c l = 2 and X r e s = 1 Press the button “ 2nd ” then “TRACE”, then select “ZERO” to find the x -intercept

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
