For the function f(x)={−x+3,x>02x+3,x≤0, what is the average rate of change over the interval 1 ≤ x ≤ 3?

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

but there’s no any figure there!

where is the graph or the picture? ?
