Question 45062: Help to show the work please.
Find the (a) domain and range, (b) determine the intervals over which the function is increasing, decreasing, or constant and (c) determine any maximum or minimum values. f(x)=2-x^2
Answer by Nate(3500) About Me  (Show Source):
You can put this solution on YOUR website!
f(x) = -x^2 + 2
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-x%5E2+%2B+2+%29+
Domain: all real numbers
Range: y+%3C=+2
x ---> -infinity, y ---> -infinity
x ---> +infinity, y ---> -infinity
Maximum Value: x = 0
