Step-by-step explanation:
![f(x) = \sqrt[3]{x - 3}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20-%203%7D)
The domain of a function are the values of
that you can plug into the function
.
Values inside of a root must be non-negative, which means that
must be greater than or equal to zero. We can set up an equation to find the domain:
![x - 3 \geq 0](https://tex.z-dn.net/?f=x%20-%203%20%5Cgeq%200)
![x \geq 3](https://tex.z-dn.net/?f=x%20%5Cgeq%203)
With this, we know the domain of the function is
.
The range of a function are the values that
can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is
.
23.) 21 hrs at $ 11 per hr = (21 * 11) = 231....and u received 91% of ur wages...
0.91 (231) = 210.21
fraction u got : 210.21 / 231 = 0.91 = 91/100 <== I am not 100% sure on
this. I might be making this harder then it looks....u r going to get 210.31 take home pay.....or 91% which in fraction form is 91/100
26B. 17/10 = 85/ x
cross multiply
17x = 850
x = 850/17
x = 50....50 liters of oil <==
26C. 12:9...added = 21
12/21(4200) = 50400/21 = 2400 <== higher cost receives 2400
9/21(4200) = 37800/21 = 1800
Line the numbers up by place value. Regroup 12 into 1 ten and 2 ones. Add the 1 ten you regrouped. Because the 2 represents tens, the numbers will start in the tens column.
Hope this helps
X=4
Y=-5
i hope that will help
Currently, the only statement that's true is that there are no 'choices' to answer the question at hand. With no reference variables for the f, g, x, or y operators, and technically, TWO separate equations at this point, the only statement that's true is that the formula in question is currently reduced (simplified) to its most simple form.
