How do you graph m² - 5m – 14 = 0 ?
----
Maybe you mean y = m^2-5m-14
----
Solve m^2-5m-14 = 0 to find the m-intercepts:
(m-7)(m+2) = 0
m = 7 or m = -2
---
The m-intercepts are (7,0) and (-2,0)
======================================
The y-intercept is (0,-14)
----
Plot those three points and sketch
a parabola opening upward thru them to get:
