Compare the function ƒ(x) = –x2 + 4x – 5 and the function g(x), whose graph is shown. Which function has a greater absolute maxi
hram777 [196]

Answer:

Answer C:  g(x)

Step-by-step explanation:

I used a graphing calculator to graph f(x) = -x^2 + 4x - 5, and by doing so I immedately saw that the vertex of f(x) is at (2, -1).

The absolute max of g(x) is approximately (3.25, 6.1).

The absolute max of f(x) is approximately (2, -1).

Since the y-coordinate of the absolute maximum of g(x) is greater than the y-coordinate of the absolute maximum of f(x), we conclude that Answer C is correct:  g(x) has the greater absolute maximum

Which solution to the equation 1/x-1 = x-2/2x^2-2 is extraneous
melamori03 [73]

<u>Solution-</u>

The equation given here,

\frac{1}{x-1} =\frac{x-2}{2x^2-2}

\Rightarrow 2x^2-2=(x-1)(x-2)

\Rightarrow 2x^2-2=x^2-3x+2

\Rightarrow x^2+3x-4=0

\Rightarrow x^2 +4x-x-4=0

\Rightarrow (x-1)(x+4)=0

\Rightarrow x=1 \ and -4

But, at x=1, \frac{1}{x-1} \ and \ \frac{x-2}{2x^2-2} becomes infinity so it can't be a solution to the equation.

∴ x=1 is the extraneous solution of the equation
