Create a table for x and y x,1,2,3y,1,5,9Draw the line on a graph

We know that this is going to be a “U” shaped parabola as the graph is a positive x^2 graph. The y intercept is the point at which x=0. Substituting in 0 gives when x = 0, y = -21.Now we need the x interc...

By completing the square we find that f(x) = x² + 2x + 2 = (x+1)² + 1Since (x+1)² is a number that has been squared, it must be greater than or equal to zero. Therefore, f...

y = x² + 3x + 2 Finding the y intercept:When x = 0, y = 2 Therefore y intercept is at (0,2)Finding x intercept:Method 1: Factorise y = x² + 3x + 2 y = (x+1)(x+2)x intercepts are when...
