conditions:x-intercept 3,and passing through the point (1,-2) 相关知识点: 试题来源: 解析 It sounds like that it passes thru 3 points: (0,0),(3,0),(1,-2)From the first 2 points,it can be expressed in the form of y = ax(x-3)It passes thru (1 -2):-2 = a*1*(1-3)...
one repeated real solutions x_1 = -b / 2a = -2 / -2 = 1 The graph of function in part b) has one x intercept at (1,0) . c) We solve -2 x 2 + 2 x - 2 = 0 discriminant D = 2 2 - 4(-2)(-2) = -12 No real solutions for the above equation ...
x-intercept: no real solutions! Thus, no x-intercept 3. Note the graph opens downward: F. Projectile Motion A thrown object follows a parabolic path given by initial upward speed initial height thrown from Units of height: feet The vertex is the peak of the path. ...

y–intercept Putting x=0;y=−(−1)(−3)=−3x=0;y=−(−1)(−3)=−3Question 1:Given the quadratic function y=(x−2)(x+4)y=(x−2)(x+4), Find the coordinates of the x-intercepts and y-intercepts. State the equation of the line of symmetry of the graph. ...
Determine the intercept The function ff intercepts the axes at the origin (0;0)(0;0). We notice that as the value of xx increases from −∞−∞ to 00, f(x)f(x) decreases. At the turning point (0;0)(0;0), f(x)=0f(x)=0. As the value of xx increases from 00 to ∞...
The parabola of the quadratic function intercepts the xx-axis at exactly one point. If the discriminant is negative (D<0D<0), the quadratic equation has 2 distinct roots and both are complex numbers. The parabola of the quadratic function does not intercept the xx-axis.Methods to solve or...
The points where it intersects the x-axis are called x-intercepts or roots. The point where it intersects the y-axis is called the y-intercept.Direction: The direction in which the parabola opens depends on the sign of the coefficient of the squared term in the quadratic function. If it'...
