Answer:
C. {1, 2, 4}
Step-by-step explanation:
In a function, the range are the values of the outputs. They are also the y-values. In a table, the range would be on the right side on the table.
According to the table, the numbers under the 'y' column are 1, 4, 4, and 2. Therefore, the range is: {1, 2, 4}.
Option C should the correct answer.
Answer:
replace x with -4
f(-4)= 4(-4) + 2
4(-4) + 2 = -16 + 2 = -14

Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2
