SUMMARY

The discussion focuses on solving for the y-coordinates of intersection between the functions f(y) = y² and g(y) = y + 2. The intersection is found by setting the two equations equal to each other, resulting in the equation y² - y - 2 = 0. This quadratic equation can be solved using the quadratic formula or factoring to find the y-values where the two functions intersect.

PREREQUISITES
  • Understanding of quadratic equations
  • Familiarity with function intersection concepts
  • Knowledge of the quadratic formula

Simple problem...need help PlEaSe!

Homework Statement


Okay so I am trying to find the area of a region but I having a problem with a simple intermediate step! I have...
f(y) = y^2
g(y) = y + 2
I need to find the y-coordinates of where the 2 lines intersect. Can someone please help me?
