Finding y-intercept, equation of the axis of symmetry, and x-coordinate of the vertex of a quadratic function
For the function f(x) = x² - 6x + 8,
Find the y-intercept, the equation of the axis of symmetry, and the x-coordinate of the vertex.
Find the point of intersection of lines L: x = 7 and M: y = -8.
a) what is the value of the y-coordinate for any x-intercept? explain.
b) find the x intercept for the following line: y = 3x - 6
How do you find the x and y intercepts of: x - 8y + 7 = 0?
