In each rotation, the length of time that the broken bucket is visible above the surface of the water can be found by analyzing the A. y-intercept B. period of the function C. difference between the two smallest positive x-intercepts D. difference between the maximum value and the minimum value of the function 6. The diameter of the water wheel is the A. y-intercept B. period of the function C. difference between the two smallest positive x-intercepts D. difference between the maximum value and the minimum value of the function
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.
