which of the following characteristics best describes the given function of f (x) = 3x - 6

Question

1) exponential function, always increasing, linear

2) linear absolute value function, always increasing, linear, maximum

3) linear function, always increasing, straight lines, no maximum or minimum

4) exponential function, always decreasing, linear

Answer 1

3) linear, always increasing, since the coefficient of the x term is positive

linear because the x term has an implicit exponent = 1

no max or min as the line goes forever approaching infinity as x grows ever larger

and the line appraches negative infinity, as x becomes decreasingly negative
