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.
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:
Answer:
trinomial
Step-by-step explanation:
Since this polynomial has 3 different terms, this is, in fact, a trinomial.
Hope this helps :)
Answer:
9
Step-by-step explanation:
f(-3)=-1/3=-3 then crisscross
-3*3=-1
-9=-1 divide by -1
f(-3)=9
