Answer:
Step-by-step explanation:
The domain is all real numbers, and the range is all
real numbers less than or equal to 4.
-20 each year
how many years? 4
-20 times number of years=drop
-20 times 4=-80
dropped by -80 total
if costs 189 before, now it is 189-80=109
costs $109.00 today
Answer:
Equation of tangent line at point (1,0) to given function is
y=x-1
Step-by-step explanation:
Equation of tangent line is
y-y₁=m(x-x₁)-----(1)
where m is slope of line and can be found by implicitly differentiating the given function w.r.to x

which is slope of tangent line. At (1,0) equation of tangent line is
