The function to be used is called "p" and represents the area of the pepper patch to be constructed. It should depend on the length of the tomatopatch (this dimension/variable is called "x")
Therefore, p(x) is how we write the function in mathematical terms.
Now, the domain of this function consists as all domains as the possible x values that could render a viable answer. so, the Domain is:
Domain = {set of all possible lengths of the tomato patch} This description better describes that given in the very first option on the top left.
The y-intercept: Recall that the variable we are representing on the y-axis (vertical axis), and the intersect occurs when the x-value is zero.
So y-intercept = The area of the pepper patch when the length of the tomato patch is zero (last option - bottom right)
x-intercepts: The points at which p is zero, So the length of the tomato patch when the area of the pepper patch is zero. (This is the bottom left option they give you).
The Range: is all possible answer for the area of the pepper patch. Which is best described by the middle top option they gave you.
