Answer:
<em>The domain of f is (-∞,4)</em>
Step-by-step explanation:
<u>Domain of a Function</u>
The domain of a function f is the set of all the values that the input variable can take so the function exists.
We are given the function
It's a rational function which denominator cannot be 0. In the denominator, there is a square root whose radicand cannot be negative, that is, 4-x must be positive or zero, but the previous restriction takes out 0 from the domain, thus:
4 - x > 0
Subtracting 4:
- x > -4
Multiplying by -1 and swapping the inequality sign:
x < 4
Thus the domain of f is (-∞,4)
I cant really see that- could you tell me what that is?
Answer:
linear function is a function whose graph is a line. Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line.
Step-by-step explanation:
Answer:
the slope is stepper and the line is shifted up
<span>The answer is twelve ten thousands. Let's find how many ten thousands are in 120,000. Ten thousand in a number form is 10,000. Now, divide 120,000 by 10,000 (ten thousand). 120,000 : 10,000 = 12. In other words, there are twelve ten thousands in 120,000.Hope this helps. Let me know if you need additional help!</span>
