Consider the following function. f(x) = 2x-4/5 State the domain of the function. (Enter your answer using interval notation.) Identify any intercepts. (If an answer does not exist, enter DNE.) Consider the following function. f(x) = 4 3SQUAREROOTx Test for symmetry. (Select all that apply.)

Solution

f(x) = (2x-4)/5

Domain : All real ( -inf, +inf)

Intercept:

X intercept: f(x) =0 and solve for x

2x -4 =0 ----> x= 2

( 2, 0)

Y intercept: Plug x=0 in f(x)

f(0) = -4/6

( 0, -4/5)
