Answer:
Let's use these two sets given to explain what is the domain.
Each value from the left set is x, and from the right is f(x).
If we plug any x from the left set in the function, we'll get f(x) that corresponds to it and that's exactly what the arrows are showing.
Domain of the function is, basically, a set of all values x can have.
In this case, it's easy to see, those are all members of the left set (-6, 1, 5, 8), but sometimes this set can have lots and lots of members, even infinity.
Answer:
t=5
f=13
Step-by-step explanation:
(5x⁴ - 3x³ + 6x) - (3x³ + 11x² - 8x)<span>
</span>Expand the second bracket by multiplying throughout by -1
5x⁴ - 3x³ + 6x - <span>3x³ - 11x² + 8x
</span>
Group like terms and simplify
5x⁴ - 3x³ - 3x³ - 11x² + 6x <span>+ 8x
</span>5x⁴ <span>- 6x</span>³ - <span>11x² + 14x</span>
Answer: $11,727.27
Step-by-step explanation:
CD: $X
Savings: $4X
Mutual: $(15,000-5X)
0.02X + 0.01*4X + 0.1(15000-5x) = 210
0.06X + 1500 - 0.5X = 210
-0.44X = 210-1500 = -1290
X = 2931.82
4X = 4*2931.82 = $11,727.27
