Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0


Here, a = 4, b = -5 and c = 8. Then,


5 plus or minus sqrt (25 -4(4)(8) )

x = ------------------------------------------------------

8

5 plus or minus sqrt (-103)

= --------------------------------------

8

5 plus or minus i*sqrt(103)

Then x = ----------------------------------------

8


= ---------------------------------------------

8

= ----------------------------

Let \[f(x) = \frac{3x - 7}{x + 1}.\]find the range of $f$. give your answer as an interval.
ra1l [238]
Hello :
let : y=  \frac{3x-7}{x+1}
calculate : x ......x <span>≠ -1 
</span>y(x+1) = 3x-7
yx+y =3x-7
yx-3x = -y-7
x(y-3) = -7-y
x =  \frac{y+7}{3-y}
the inverse function is : g(x) =  \frac{x+7}{3-x}
domain of : g  is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[
