Answer:
b. y ≤ 0
Step-by-step explanation:
Do you mean f(x) = -x^2?
If so, think of f(x) = x^2. You can use any real number for x. Once you square each value of x, you can get zero or a positive real for y. f(x) can only be a non-negative number. Now look at your function: f(x) = -x^2. The values of y are the opposite of the values of y in f(x) = x^2, so the range of f(x) = -x^2 is zero and all negative reals.
Answer: b. y ≤ 0
Convert 1/5 to a decimal so we can compare two decimals.
1/5= 20/100= 0.20
Then compare 0.2 vs 0.25
0.2<0.25
Final answer: 0.25>(1/5)
Answer:
C.Yes, because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
A function is a relation in which each element of the domain (x) is mapped to one element of the range (y). This means that no x can be mapped to more than one y; basically it means that no x can repeat.
In this table, no x repeats; each x is mapped to only 1 y. This means that it is a function.
Answer:
Step-by-step explanation:
The sides for the square are equal to 2x-5 because that is the square root of the area. The length of the rectangle is 3x+6 and the width is 3x-6 because that is what you get when you factor the equation.
Now, you have add them up.
To take out the line in the middle of the shape we will subtract 
because we are assuming that this equation is equal to the shorter side. This makes the equation
If you are looking for a numerical answer, I can't say I know how to get it.
Hope this helps! <3
