F(x)'s domain is the extent of its x-values and the function x^2 + 3 extends to infinity and negative infinity so its domain is all real #s,
f(x)'s range is its y-values and f(x) is only defined for and values above 3, so its range is y>= 3
f(x)^-1 is the function (x-3)^(1/2) which is a square root function and x >= 3 because if x were to be 2 there would be a negative in the square root which means the y-value would be on the imaginary axis.
the range is y>= 0 because the output of the square root function can never be negative in this context as it is not being multiplied by a negative on the front
This is a fairly simple problem to do. Since you already know how many acres of corn can be harvested in a day then just multiply 10.5 (because of that being however many days being harvested) by 2 1/3. 10.5*2 1/3=24.5. Mr. Bond can harvest 24.5 or 24 1/2 acres of corn in 10.5 days.
Answer:

Step-by-step explanation:
Let's start by taking a look at the blue line. The slope of any line that passes through two points is equal to the change in y-values over the change in x-values. We can see that the line passes through points (0, 1) and (1, 0). Assign these points to
and
(doesn't matter which you assign) and use the slope formula:

Let:

The slope is equal to:

Therefore, the slope of this line is -1. In slope-intercept form
,
represents slope, so one of the lines must have a term with
in it, which eliminates answer choices A and D.
For the second line, do the same thing. The red line clearly passes through (0, -3) and (3, -2). Therefore, let:

Using the slope formula:

Thus, the slope of the line is 1/3 and the other line must have a term with
in it, eliminating answer choice C and leaving the answer 
*You can find the exact equation of each line by using the slope formula as shown and plugging in any point the line passes through into
