Find the intercepts and vertex of y = −x2 + 2x − 4, and graph the parabola.To find the vertex, I look at the coefficients: a = −1 and b = 2. Then I plug these into the formula for the first coordinate of the vertex: To find k (the second coordinate of the vertex),...
It is a parabolaExample: Satellite Dish Shape Many satellite dishes have a parabolic shape, which helps focus signals to the receiver But we will need to use f(x) = ax2Let us see what happens when we introduce the "a" value:f(x) = ax2Larger...
