Answer:

None of these statements are true.

Step-by-step explanation:

a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.

b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.

c) for y = √f(x), y' = f'(x)/(2√f(x))

**PLEASE HELP ASAP** Terri is analyzing a circle, y^2 + x^2 = 36, and a linear function g(x). Will they intersect?

Alborosie

We analyze the linear function to find that it has equation $y=x$ . Drawing the line, we find that it will intersect the circle at negative and positive x-coordinates.

We can prove this by substituting $y=x$ into the given equation:

$x^2+x^2=36$

$2x^2=36$

$x^2 = 18$

$x = \pm 3\sqrt{2}$

Hence, $x = 3\sqrt{2}$ or $-\sqrt{2}$ , so there are both positive and negative values for $x$ .

levacccp [35]

Answer:

perpendicular

Step-by-step explanation:

The graph of x = 4 is a vertical line and the graph of y = 3 is a horizontal line.

Vertical and horizontal lines are perpendicular.
