DedPeter [7]
A ratio is not multiplication, so I'm just going to throw that out there first in case any other answers trip you up.

9:2 is the correct answer because there are 9 sandwiches for 2 people.

Part A:

The plot for the function f(x) and g(x) is attached. The purple curve represents f(x) and the black line represents g(x).



Part B:

The graph of f(x) shows that f(x) is an exponential function.
The graph of g(x) shows that g(x) is a linear function.



Part C:

As x increases from left to right, the function f(x) increases very rapidly.
As x increases from left to right, the function f(x) increases at a constant rate.



Part D:

From the graph it can be seen than the valus of x for which the values of the function are equal are: x = -4 and x = 1.19.

Find inverse of f(x)=3x+1
Ratling [72]
First, replace f(x) with y.

So we have now:

y = 3x + 1

Next, switch the x and y.

We get:

x = 3y + 1

Finally, solve for y.

3y = x - 1

y = x/3 - 1/3

So, we have f(x) = 3x + 1, and the inverse of this function is:

\boxed{f^{-1}(x) = \frac{1}{3} x - \frac{1}{3}}\\\\OR\\\\\boxed{f^{-1}(x) = \frac{x-1}{3}}
