If f(x)=3x5−10x3+5, on what intervals is f″(x)>0?
Ksivusya [100]

Answer:

(0.7937,\infty)

Step-by-step explanation:

we are given an algebraic function in x, such that

f(x) = 3x^5-10x^3+5

To find when second derivative >0

For this let us find first and second derivative by successive differentiation.

f(x) = 3x^5-10x^3+5\\f'(x) =15x^4-30x^2\\f'(x)=60x^3-30

when ii derivative >0 we have

60x^3-30>0

x^3>0.5\\x>0.7937

f"(x)>0 in

(0.7937,\infty)

The graph of a linear relationship is shown. Which equation best represents the relationship between x and y in the graph
Finger [1]

Answer:

B.  y = -3/4x + 5/2

Step-by-step explanation:

Take two points from the graph, let's use (-2, 4) and (2, 1):

Find slope:

 m = (y₂ - y₁) / (x₂ - x₁)

     = (1 - 4) / (2 - (-2))

     = -3/4

Find y-intercept using slope above and anyone point:

y = mx + b

(1) = -3/4(2) + b

1 = -3/2 + b

b = 1 + 3/2

b = 5/2

Equation of line using m and b above:

y = mx + b

y = -3/4x + 5/2
