SUMMARY

The discussion focuses on identifying the x-intercepts of the parabola defined by the equation y = (x + 2)² - 3. To find the x-intercepts, one must set y to zero and solve for x, leading to the equation (x + 2)² - 3 = 0. The solution involves understanding the definitions of x-intercepts and y-intercepts, which are critical for solving such problems effectively.

PREREQUISITES
  • Understanding of quadratic equations
  • Knowledge of the vertex form of a parabola
  • Familiarity with solving equations for specific variables
  • Basic definitions of x-intercepts and y-intercepts
NEXT STEPS

Homework Statement


Identify the x-intercept(s) of the parabola y = (x + 2)2 – 3


Homework Equations





The Attempt at a Solution


No idea on where to begin and if I would do the same thing with y
 
Physics news on Phys.org
to find the y intercepts, let x=0,
so to find the x intercepts let what=0?
 
When you have "no idea where to begin" you probably don't understand some of words in the problem. In a case like that it is always a good idea to review the definitions: what do "x-intercept" and "y-intercept" mean?
