He says that the plotted point is mc021-2.jpg. what is raj’s error?
a. the x-coordinate should be -4.
b. the y-coordinate should be 1.5.
c. the x- and y-coordinates are switched.
d. both coordinates should be positive.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

what

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
