Note that the from
to 0, that is the left part, the function is the line y=1.
Similarly, from 0 (not included) to
, the function is y=-1.
Thus the function is given by the rule:
y=1, for x≤0,
y=-1, for x>0.
Remark: a horizontal line at height c, from the x-axis, is the graph of the function y=c.
Answer:
i have know idea
Step-by-step explanation:
Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
A = b√x+c
a/b = √x+c
(a/b)^2 = x + c
(a/b)^2 - x = c
