In the function y=[x]-1, which values of the function are equivalent?
f(-1) and f(-2)
f(1) and f(o)
f(-3) and f(-2.1)
f(2) and f(1.9)

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

i believe it's a.

i'm not sure on this one, most likely correct.

one peck is 9.309 quarts

9.309x 2

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.
