Homework Statement
Find at what points these two functions intercept.
y=x+1 y=9-(x^2)
Homework Equations
x+1=9-(x^2)
The Attempt at a Solution
(x^2)-x-8=0
The discussion focuses on finding the intersection points of the functions y = x + 1 and y = 9 - (x^2). The equation derived from setting these functions equal is x^2 - x - 8 = 0. To solve this quadratic equation, participants suggest using either the quadratic formula or completing the square, emphasizing the importance of checking the sign on the x term for accuracy.
PREREQUISITESStudents studying algebra, mathematics educators, and anyone looking to improve their skills in solving quadratic equations and understanding function intersections.
LCKurtz said:I assume you mean "intersect". Either complete the square or use the quadratic formula. And check the sign on your x term.
