What is the x-intercept for the following equation y=2(x+1)^2 + 3? Please show step by step.
~~~~~~~~~~~~~~~
In this post, y = 2(x+1)^2 + 3 IS NOT an equation.
This equality is the DEFINITION of function y.
Use the terms correctly, precisely with their destiny and meaning.
The quadratic term 2*(x+1)^2 is always non-negative.
With the constant term "3" added, the function y = 2*(x+1)^2 + 3 is always positive.
So the graph of the function y = 2(x+1)^2 + 3 HAS NO x-intercept. ANSWER
