IMPORTANT - requires printpts stored in the same folder as your current folder or in the “library” folder (see the Variable Manager).
axisints(f, l, u)
- f is an expression in terms of x
- l is the lower boundary of x (l should not be in terms of unknown variables, and should be -∞ if f contains other unknown variables besides x)
- u is the upper boundary of x (u should not be in terms of unknown variables, and should be ∞ if f contains other unknown variables besides x)
Returns a list of coordinates of x-axis and y-axis intercepts on f in the domain xϵ[l, u].
Example
Let \(f(x)=8-2^{x-1}\). Find the area bound by the graph of \(f(x)\) and the line connecting the axis intercepts of \(f(x)\). (2019 NHT Methods Exam 2 Section A Question 18)
This solution also uses lineof.
