Let f be defined as shown. Which statement is true?
Click on the correct answer.

The inverse of f exists.

The inverse of f does not exist.

I believe the answer is The inverse of f exists

Step-by-step explanation:

F is defined as a function since each value matches up to their own. No 2 numbers are matched to the same number. If that is the case, the an inverse of f exists because it can be traced back towards 1 number.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
