This is a polynomial function called Quadratic Function. This is written as:
Recall that the graph of a quadratic function is a special type of U-shaped curve called parabola. The graph of this function is shown in the Figure below. From that, we can say the following:
A. The domain is all real numbers.
This is true. In fact, the domain of any polynomial function is the set of all real numbers.
B. The range is all real numbers greater than or equal to 1.
This is false. Instead, the range is all real numbers greater than or equal to 2, that is the of the vertex.
C. The y-intercept is 3.
This is true. We can find the letting , so:
D. The graph of the function is 1 unit up and 2 units to the left from the graph of
This is false. The correct statement is that the graph of the function is 2 units up and 1 unit to the left from the graph of
E. The graph has two x-intercepts.
This is false. As shown the graph below, this function does not have any
Answer:
A and C
Step-by-step explanation:
O {x|1 < x < 4}
O {x|2 < x < 4}
Find theta to the nearest degree in the interval 0° less than or equal to theta less than or equal to 360°
To find out how much flour Ricky needs, we first need to find 1 1/2 times the amount of flour in the original recipe.
2 3/3 cups of flour is the same as 8/3 cups of flour.
To find 1 1/2 times the amount of flour in the original recipe, we can multiply 8/3 by 1 1/2:
8/3 x 3/2 = 24/6 + 4/6 = 28/6
So 1 1/2 times the amount of flour in the original recipe is 28/6 cups of flour.
To find out how much flour Ricky needs, we can multiply this amount by 1 1/2:
28/6 x 3/2 = 84/12 + 18/12 = 102/12
So Ricky needs 102/12 cups of flour, which simplifies to 8 1/2 cups of flour.
