Q4. Consider the functions

f(x) = and g(x) = [0, 0≤x x<0

1, 0≤x

In each part, is the given function continuous at x =

0?

(a) f(x) (b) g(x) (c) f(-x) (d) [g(x)]

(e) f(x)g(x) (f) g(f(x)) (g) f(x) + g(x)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
