Answer:

28.85714285714286 is the answer.

Step-by-step explanation:

First, figure the out the answer to 5x9. 5x9=45. So, multiply 45x45= 2,025 and then divide 2,025 by 5x3 but five time three equals 15. So, divide 2,025 by 15 and you get 135 and you add 67 to 135 and the sum is 202. Then, you divide 202 by 7 and you get 28.85714285714286.

svetlana [45]

Derivatives can be calculated from graphed functions.

The values of the derivatives are:

The given parameter is:

\mathbf{h(x) = f(g(x))}

Start by calculating the equations of f(x) and g(x)

<u>Graph f(x)</u>

The slopes of f(x) are: 3/2 and -3/2

So, the equations are:

\mathbf{f(x) = \frac{3}{2}x,\ 0 \le x \le 2}

\mathbf{f(x) = -\frac{3}{2}x,\  x \ge 2}

<u>Graph g(x)</u>

The slope of g(x) is: -1/2

So, the equation is:

\mathbf{g(x) = -\frac 12x}

<u>For x = 1 and x = 2, we have:</u>

So, we have:

\mathbf{h(x) = f(g(x))}

Where:

\mathbf{f(x) = \frac{3}{2}x\ 0 \le x \le 2} and \mathbf{g(x) = -\frac 12x}

\mathbf{h(x) = f(g(x))} becomes

\mathbf{h(x) = \frac{3}{2}(-\frac{1}{2}x)}

Open brackets

\mathbf{h(x) = -\frac{3}{4}x}

Differentiate

\mathbf{h'(x) = -\frac{3}{4}}

So:

\mathbf{h'(1) = -\frac{3}{4}}

\mathbf{h'(2) = -\frac{3}{4}}

For x = 3, we have:

\mathbf{h(x) = f(g(x))}

Where:

\mathbf{f(x) = -\frac{3}{2}x\  x \ge 2} and \mathbf{g(x) = -\frac 12x}

\mathbf{h(x) = f(g(x))} becomes

\mathbf{h(x) = -\frac{3}{2}(-\frac{1}{2}x)}

\mathbf{h(x) = \frac{3}{4}x}

Differentiate

\mathbf{h'(x) = \frac{3}{4}}

Substitute 3 for x

\mathbf{h'(3) = \frac{3}{4}}

Hence, the values of the derivatives are:

\mathbf{h'(1) = -\frac{3}{4}}, \mathbf{h'(2) = -\frac{3}{4}} and \mathbf{h'(3) = \frac{3}{4}}
