Question

The domain and range of the real function f defined by f(x) 4-x/ X-4 given by (a) Domain = R, Range {-1, 1} (b) Domain = R- {1}, Range R (c) Domain = R- (4}, Range {-1} (d) Domain = R - (-4), Range {-1,1}

Answer 1

Step-by-step explanation:

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,1)∪(1,∞),{x|x≠1}(-∞,1)∪(1,∞),{x|x≠1}

Range: (−∞,0)∪(0,∞),{y|y≠0}
