2.3: Curve Intersection
( \newcommand{\kernel}{\mathrm{null}\,}\)
Intersection of Lines
Recall that if we want to find the intersection point of two lines, we have two choices: substitution and elimination.
x=5−2(2)=1.
y=3.
Intersection of Other Curves
y=−75 or y=4.
We get the points
(−245,−75) and (3,4).
(2,√7),(−2,√7),(2,−√7),(−2,−√7).
To find the intersection we just use the intersection function on the graphing calculator.
