WebExample 1: Find the x-intercept of the function y = x 2 - 7x + 10. Solution: To find: The x-intercept of the function y = x 2 - 7x + 10. Using the formula to find x-intercept, to find the x-intercept, we just substitute y = 0 in the given equation and solve for x. 0 = x 2 - 7x + 10 0 = (x - 2) (x - 5) x - 2 = 0; x - 5 = 0 x = 2; x = 5 WebA worked example of simplifying an expression that is a sum of several radicals.

WebSince k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x. Example 1: If y varies directly as x, and x = 12 ... WebOct 6, 2024 · To find the y -intercept, set x = 0 and determine the corresponding y -value.
