Answer:
A
Step-by-step explanation:
it says it is currently at 60 watts, if its tripled (times 3) that meansits times 3 and 60 times 3 is 180 so its A therefore.
Answer: Domain of the given function is all real numbers.
Range of the given function is {y | y>=1}
Step-by-step explanation:
The given function is a polynomial and the domain of any polynomial is all the real numbers because for any value of x, the function will have some value.
Hence, the domain will be all real numbers.
Range is the set of y values for which the function is defined.
This is a polynomial and to find the range, we will simplify the polynomial.

Therefore, for any value of x, f(x) ≥ 1
Hence, the range becomes {y | y ≥ 1}
The correct answer would be
A. y = 0.5x + 4.5
Answer:
(x^2-6)^2
Step-by-step explanation:
Answer:

Step-by-step explanation:
For any square, A = side x side, or "side squared"
If area is given, reverse the process-- take the square root of the Area.
in this question "b" is the side,
so substitute the value and solve
6 = b
