The graph of a twice differential function is shown at right. Which of the following is true?

Answers

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)

The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.

What is a differential function?

A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

Given:

The coordinate of the graph is shown in figure  (2, 0),

As we can see from the graph, the slope: f' (2) is negative (Downwards)

Again, from the graph

f(2) = 0

Thus, the curve concave upward: f'' (2) is positive (upward)

f' (2)<0

f (2)=0

0 < f'' (2)

f' (2) < 0 < f'' (2)

Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

HELP ME PLS ASAP PLS PLZ PLZ PLS

Answers

Answer:

78cm^2

Step-by-step explanation:

You'd want to separate the two shapes into a rectangle and triangle. So you'd have one rectangle with one side being 2 and the long side 12. (2 * 12 = 24). Then a triangle with a base of 9 and a height of 12. (9 * 12 = 108 / 2 = 54) Then you add both areas together to get 54 + 24 = 78.

Answer:

B: 78

Step-by-step explanation:

cut it in half into a rectangle and traingle

the rectangles area is 2x12=24

The area of the triangle is 9x12=108   108/2 = 54

then add the 2 areas to get B:78
