Review Notes for Calculus I Intercepts: X-intercept: where the graph intersects the x-axis (in the coordinates for an x-intercept, the y-value is always 0, ex: (7, 0).) o To find x-intercepts, replace y with 0. Y-Intercept: where the graph intersects the y-axis (in the coordinates for a y-intercept, the x-value is always 0, ex: (0, 8).) o To find the y-intercepts, replace x with 0. Ex: y=x -4x X-in3ercept y=x -4x 0=x -4x (Replace y with 0) 0=x(x -4) (Factor out a Greatest Common Factor between x 3 and 4x) 0=x(x-2) (x-2) (Complete the square) X=0, 2, -2 (Solve for x) Y-
