Find the domain and range of f(x) = |x| + cosx A. domain: (-infinity, infinity); range: (-infinity, infinity)

B. domain: (-infinity ,1]; range: (- infinity, infinity)

C. domain: (-infinity, infinity); range: (-infinity, 1]

D. domain: (-infinity, infinity); range: [1, infinity)

D. domain: (-infinity, infinity); range: [1, infinity)

Step-by-step explanation:

The domain is the values that x can take

The domain is (-infinity, infinity)

The range is the values that y can take

absolute value is 0 or greater

cos x is from -1 to 1

The minimum value is when x=0

The smallest value is 1 and the largest is infinity

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

your answer would be 12
