rcise 2.2: Let ƒ(x) = x³ - 5x² + 10x + 15, g(x) = -x³ + 3x² + 16x − 21 be two
tions.
a) Both functions have a launch point that through it is passing a tangent line to both
functions. Find the equation of this line. (Remark: you can find the equation line by
the formula y - y₁ = m(x-x₁)
where (x₁, y₁) is a point on the line and m its slope)
b) Find the equation of the lines which are parallel to each other, and they are tangent
line to the functions above, such that the line that connects their launch points is
parallel to the y-axis.
