The ball reaches a maximum height of 140 feet. c. To find when the ball hits the ground, we need to determine when the height is zero,H(t)=0.H(t)=0. We use the quadratic formula. ⎧⎪ ⎪⎨⎪ ⎪⎩t=−80±√802−4(−16)(40)2(−...

draw the graph of this function we shall get a parabola with vertex (h,k). The parabola will be upward for a>0 and downward for a<0 Maximum and Minimum value of a quadratic function-If the function is in the form Then ‘h’ isthe input value of the function while ‘k’ is itsou...
For maximum and minimum problem of a quadratic function of n variables without restricted conditions , we obtained both concise sufficient and necessary conditions for existence of maximum (or minimum) and existence and uniqueness of maximum (or minimum) point. The problem with m{m 孙华...

Learners must be able to determine the equation of a function from a given graph. Discuss and explain the characteristics of functions: domain, range, intercepts with the axes, maximum and minimum values, symmetry, etc. Emphasize to learners the importance of examining the equation of a function...
For a < 0, the parabola y = f(x) opens upward and has maximum value at x = -b/2a f(-b/2a) = -D/4a Range=(∞,-D/4a)Sign of Quadratic Equation 1. If b2 - 4ac = 0 (double root case), then we have ax2 + bx + c = a(x+b/2a)2 In this case, the function f(...
The domain of a quadratic function consists entirely of real numbers. If the vertex is a minimum, the range is all real numbers greater than or equal to they-value. If the vertex is a maximum, the range is all real numbers less than or equal to they-value. ...
Now, consider f(x) = 4x-11; Here a = 0, therefore f(x) is NOT a quadratic function. Vertex of Quadratic Function The vertex of a quadratic function (which is in U shape) is where thefunctionhas a maximum value or a minimum value. Theaxis of symmetryof the quadratic function interse...
