1 answer:

6 0

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tan function is cotan

Cotx=1\tanx

1 is in picture above.

$average \: rate = \frac{f(4) - f(1)}{4 - ( - 1)} = \frac{5}{4 - ( - 1)} = 1$

3. In the picture...

4. In the picture...

5. Parts A and B are true.

$average \: rate = \frac{f(0) - f( - 10)}{0 - ( - 10)} = \frac{( - 6) - 184}{0 - ( - 10)} = \frac{ - 190}{10} = - 19$

7. The axis symmetry equation of

$y = a {x}^{2} + bx + c$

$x = \frac{ - b}{2a}$

So it would be x=-3/4

$y = {(x - 6)}^{2} + 10$

Answer:

C. symmetric with respect to the origin

Step-by-step explanation:

A graph must pass the vertical line test to be called the graph of a function. No function will ever be symmetrical with respect to the x-axis, because that would mean it fails the vertical line test.

An even function is symmetrical about the y-axis. An even function has the characteristic that ...

f(-x) = f(x) . . . . an even function

An odd function is symmetrical about the origin. An odd function has the characteristic that ...

f(-x) = -f(x)

The given function is f(x) = -1/x. Then the value of f(-x) is ...

f(-x) = -1/-x = 1/x = -f(x)

The given function is an odd function, so is symmetrical about the origin.
