The function we have is:

f(x)=\frac{1}{2}(x-7)^3+6

Since this is a cubic function, we start with the parent cubic function (the simplest form of the cubic function):

f(x)=x^3

And compare it to the given function.

The first thing we can note is that there was a subtraction of 7 to the value of x:

x\longrightarrow x-7

When we add a number to the x value, the graph moves to the left, and when we subtract a number to the x value, the graph moves to the right.

So the first transformation is moving to the right 7 units.

Next, we have that there was +6 added to the expression --> When you add a number to the function, the graph moves up, and when you subtract a number to the function, the graph moves down.

In this case, since we added a constant value of 6, the graph is translated 6 units up.

The second transformation is moving up 6 units.

Finally, let's analyze the effect that the 1/2 has on the function.

We can compress or stretch the graph of a function by multiplying the x by a constant (a number). If the number of between 0 and 1, there is a stretch, and if the number is greater than 1 there is compression.

In this case, the number next to the x is:

\frac{1}{2}=0.5

Since the number is between 0 and 1 there is a stretch of the function.

In summary:

Answer:

Translation of 7 units to the right

Translation of 6 units up

Stretch of the function of 0.5

Would you need to use the chain rule to find the derivative of this function?
Nutka1998 [239]

Answer:

TRUE. We need to use the chain rule to find the derivative of the given function.

Step-by-step explanation:

Chain rule to find the derivative,

We have to find the derivative of F(x)

If F(x) = f[g(x)]

Then F'(x) = f'[g(x)].g'(x)

Given function is,

y = \sqrt{2x+3}

Here g(x) = (2x + 3)

and f[g(x)] = \sqrt{2x+3}

\frac{dy}{dx}=\frac{d}{dx}(\sqrt{2x+3}).\frac{d}{dx} (2x+3)

y' = \frac{1}{2}(2x+3)^{(1-\frac{1}{2})}.(2)

   = (2x+3)^{-\frac{1}{2}}

y' = \frac{1}{\sqrt{2x+3}}

Therefore, it's true that we need to use the chain rule to find the derivative of the given function.

Find f(-5) of f (x) = x + 1<br> 1) 4<br> 2) 5<br> 6) 6
Alex
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

Ben drove 230 kilometers in 3 hours, and Pia drove 250
Drupady [299]

9514 1404 393

Answer:

  Pia drove faster

Step-by-step explanation:

Speed is the ratio of distance to time. If the time is the same, the greater distance is associated with the greater speed.

Pia drove farther in 3 hours, so drove faster.
