The answer will depend on the ranges for x and y. If the ranges are not restricted, then C can have any value.

The question is not clear. A function is defined by an equation and that requires an equals sign. there is no equals sign in the question. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals".
determine whether each relation is a function y equals -8
-1
A linear function. It is a horizontal line at -7.
There is no maximum but te minimum is 15.
+3 and -3
y = -9
It has an absolute minimum at the point (2,3). It has no maximum but the ends of the graph both approach infinity.
Since the range of the cosine function is (-1,1), the function y = cos(x) assumes a minimum value of -1 for y.

No. 1a and 3d are linear, but 2bc is not. ■
A straight line has no turning points and so no local maxima or minima. The line has a maximum at + infinity and a minimum at - infinity if m > 0 and conversely if m < 0. When m = 0, the line is horizontal and so has no maximum or minimum. ([Alternatively, every point on the line is simultaneously a maximum and a minimum.]
The amplitude of a function is half the distance between the maximum and minimum values. This is the absolute value of the number in front of the trig function. for example, y=Asin(x) or y= Acos(x) the absolute value of A is the amplitude. Therefore, the amplitude of y=-2sinx is 2
