Meaning there's only 1 real root, complete the square and you get the answer.
We're going to use this formula, so if x² = 4x² then x = 2x
and if y² = 1 then y = 1
Straight to formula
Because (2x+1)² is basically (2x+1)(2x+1), we get the same value of x.
So the answer is x = -1/2
(When D>0, there are 2 real roots.)
(When D=0, there are only 1 real root.)
(When D<0, there are no real roots, but 2 complex roots.)
Answer:
The range of the function is
B. is all real numbers except
Step-by-step explanation:
Given functions:
To find the range of .
Solution:
In order to find , we will plugin
in function
.
The graph of the function shows that
1) As approaches -3 (but never touches the line
),
tends to positive or negative infinity.
2) As approaches 0 (but never touches the line
) ,
tends to positive or negative infinity.
Thus, the range of the function is all real numbers except
