Step-by-step explanation:
The range of a function y = f(x) is the set of values y takes for all values of x within the domain of f. The graph of any quadratic function, of the form f(x) = a x2 + b x + c, which can be written in vertex form as follows. f(x) = a(x - h)2 + k where h = - b / 2a and k = f(h) is either a parabola opening up, when a > 0, or a parabola opening down, when a < 0

Step-by-step explanation:
14z-3-6-52 (Add all the numbers with the negative sign together)
= 14z-61 (Equation equals 0)
0 = 14z - 61 (Add 61 to zero)
0+61 = 14z ( Note :- the negative sign before 61 changes to +ve upon moving to the left hand side)
61 = 14z (Divide both sides by 14)
61/14 = 14/14
4.357 = z
z = 4.36
