Jorge's Class
Daily Updated Notes
Started Off...Started off class with another warm up, focusing on square roots to get better practice with them. We then went over with what learned about how to graph quadratics at a faster pace with doing little work. A worksheet was then passed out as a practice sheet, which is still unknown when it'll be due. Notesx intercept - factor out the equation, making each one equal to zero y intercept - will always be the last number on the equation (or the c) up or down - if the first number/constant is positive, the parabola will be in a smiley form unless it is negative and it'll be in a frown vertex - (-b)/2a this the equation to find out out the vertex of your quadratic equation. ex; x^2+3x-4 ---> b = 3 ---> -3/2(1) = -1.5 *this is your x coordinate of your vertex (-1.5)^2+3(-1.5)-4 ---> -2.25-4.5-4 = -10.75 *your y coordinate of your vertex vertex =(-1.5,-10.75)
