Answer:
2x² + 
x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 
- 2 + 2x² + x - 3 ← collect like terms
= 2x² + x - 5
Answer:
B. He added 5 to each side of the equation.
Step-by-step explanation:
B. He added 5 to each side of the equation.
Interval notation uses parenthesis ( or ) for points that are not included in the function (open circle) and brackets [ or ] for points that are included in the function (filled in circle).
Remember that the domain for a function is the range of x-values in a function.
Interval notation includes the numbers at the each end of a continuous function. For function F, the leftmost x-value is 0. The rightmost x-value is 8. Both points at x = 0 and x = 8 are included in the function (filled in circles), so you would use the brackets. The entire function is continuous between those two points.
That means the interval notation for the domain of F is:
[0, 8]
------
Answer: [0, 8]
Answer:
Option D
Step-by-step explanation:
The volume is the product of three dimensions of the prism:
So the option D is correct
F(x) = ln (6-x); find the domain.
The domain of the "ln" function is (0, infinity), or "x is greater than zero."
Thus, the domain of the given function is "(6-x) is greater than zero."
Solve this: 6-x > 0. Add x to both sides. Then 6 > x, or x < 6 (answer)
