What are the approximate values of the minimum and maximum points of
Katen [24]
To start off, you can divide the right side of the equation by x to get rid of most of the x's so you get the polynomial x^4 - 10x^2 + 9. This means that f(x) = x^4 - 10x^2 + 9x. By factoring the right side of the equation, you get f(x) = (x^2 - 1)(x^2 - 9). I think the minimum value is 1 and the maximum value is 3.

What is the difference between a square root and dividing by 2?
Alex_Xolod [135]

ivolga24 [154]

Answer:

C is correct, D might be correct if you forgot 000 at the end of the question.

Step-by-step explanation:

005  = 5x1  so A is incorrect

945 = 9x100 +  4x10 +   5x1 so B is incorrect

15.859 = 1x10 +  5x1 +  8/10 +  5/100 +  9/1000 +  so C is correct

973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
