Let f (x) be an odd function on R, and f (x + 2) = negative f (x). When x is greater than or equal to 0 and less than or equal to 1, f (x) = x, then what is f (7.5) equal to

Let f (x) be an odd function on R, and f (x + 2) = negative f (x). When x is greater than or equal to 0 and less than or equal to 1, f (x) = x, then what is f (7.5) equal to

f(7.5)
=f(5.5+2)
=-f(5.5)
=-f(3.5+2)
=-[-f(3.5)]
=f(3.5)
=f(1.5+2)
=-f(1.5)
=-f(-0.5+2)
=-[-f(-0.5)]
=f(-0.5)
Odd function
=-f(0.5)
