Evaluate the function and enter your answer in the space provided.

Question

f(x)=4−3x

Answer 1

f(x) = 4-3x

is a one-to-one function

It satisfies the vertical line and horizontal line tests

It's impossible to cut the graph in more than one point, with a vertical or horizontal line

It has slope =-3, it's a downward sloping straight line

with y intercept = 4

4-3x =0

3x = 4

x = 4/3 = the only zero or x-intercept

domain and range are all real numbers

there are no local or global maximums or minimums.

as x approaches negative infinity, f(x) approaches +infinity.

as x approaches + infinity, f(x) appropaches -infinity
