what's the trouble? Just plug in the value
h(r) = 1/r + 2
h(0) = 1/0 + 2 is undefined
h(-1) = 1/-1 + 2 = 1
...
h(x^2) = 1/x^2 + 2 = (1+2x^2)/x^2
h(x^2+1) = 1/(x^2+1)+2 = (2x^2 + 3)/(x^2+1)
h(x^2) + 1 = 1/x^2 + 2 + 1 =(1+3x^2)/x^2
Given
h(r) = (1/r) + 2,find the following.
a) h(0)
b) h(-1)
c) h(-3)
d) h(x^2)
e) h(x^2 + 1)
f) h(x^2) + 1
Thank You
