Answer:
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 + 4x - 21.
This function has a graph which is a parabola that opens up.
Its vertex is found by completing the square:
x² + 4x + 4 - 4 - 21, or
(x + 2)² - 25
Comparing this to the standard equation
(x - h)² + k, we see that h = -2 and k = -25.
Thus, the vertex (and the minimum of this function) is (-2, -25).
Thus, the range is [-25, ∞ ). This being a polynomial function, it has no restrictions on the domain: the domain is (-∞, ∞ )
Answer:
Option a is correct.
Step-by-step explanation:
Since both fiber and sugar are types of carbohydrates and it is given that a portion of food has 24 gm of total carbohydrate and within which 2 gm of fiber and 12 gm of sugar.
Therefore, this food contains 2 g of fiber, 12 g of sugars, and 10 g of other unnamed carbohydrates, for a total of 24 g.
Hence, option (a) is correct. (Answer)
Answer:
The slope of the linear equation is 0.1998, and it means that the calories in a beef hot dog is increasing with the rate of 0.1998 calories per milligram of sodium.
Step-by-step explanation:
- Using y = mx + b, we know that m represents the slope.
- Looking at the equation of c = 0.1998s + 76.4520, our m is equal to 0.1998.
- This slope means that the rate is increasing by 0.1998 calories for every milligram of sodium.
