SP#1 Unit: E Concept:1: Parts of a Graph
The problem that you see in the image is a problem about identifying x-intercepts, y-intercepts, vertex (max/min), axis of quadratics and graphing them. Some back ground information would be on "Parts of the Graph of a Quadratic,"for example the vertex is (h,k), the x intercept is y=0, y-intercepts would be x=0, and the axis of symmetry would be the vertical line x=h. The equations given will start off in standard form which is f(x)=ax^2+bx+c but we must complete the square to put it into parent function for which is f(x)=a(x-h)^2+k
In order to solve this problem you have to pay attention to the 7 that can be factored out of the equation and the fact that you have t subtract a 56 from both sides. Once that is done you have to make sure that you get the value of b and take half and then square it so it should be a 9 since half of 6 is 3 and 3squared is 9. Just keep an eye out on your calculations.
