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:
23.5
Step-by-step explanation:
Beacuse 235.55 and 10% equals 23.5
Hello :
f(x) = (2x-5)/3
<span>f−1(x) = (3x+5)/2
because : f(x) 0 </span>f−1(x) = x and f−1(x) 0 f(x) = x
f(x) 0 f−1(x) = f( f−1(x) ) = f ((3x+5)/2) = (2(3x+5)/2 - 5))/3 = 3x /3 =x
same cacul for : f−1(x) 0 f(x) = x
Answer:
Last option
−1 • f(x)
Step-by-step explanation:
The function
passes through point (-1, 2) because:

and also goes through the point (0, 1)
Because:

Then, if the transformed function passes through the point (0, -1) and passes through the point (-1, -2) then this means that the graph of
reflected on the axis x. This means that if the point
belongs to f(x), then the point
belongs to the transformed function
The transformation that reflects the graph of a function on the x-axis is.

Where c is a negative number. In this case 
Then the transformation is:

and the transformed function is:
