Were does the graph of y equals -0.5x-2 cross the x-axis?
1.5
Where does the graph of x2 - x - 2 y cross the x-axis?
y = x^2 - x - 2 This is the graph of a parabola. We need to find the x-intercepts. Set 0 for y, and solve for x: 0 = x^2 - x - 2 0 = (x + 1)(x - 2) x + 1 = 0 or x - 2 = 0 x = -1 or x = 2 Thus, x-intercepts are -1 and 2. The graph of y = x^2 - x - 2 crosses the x-axis at x = -1 and x = 2.
An equation of the axis of symmetry of the graph y equals -x2 plus 8x-7?
y = x2 + 8x - 7 a = 1, b = 8, c = -7 the equation of the axis of symmetry: x = -b/2a x = -8/(2*1) = -4
Where does the graph of y 6x2 11x 10 cross the x-axis?
If you mean: y = 6x^2+11x-10 then x = 2/3 and x = -5/2
How many times does the graph intersect the x axis if the discriminant?
If D > 0 then the graph intersects the x-axis 2 times.If D = 0 then the the x-axis is tangent to the graph.If D < 0 then the graph doe not intersects the x-axis.
