Answer:
2 1/4
Step-by-step explanation:
To find the difference, we must subtract the smaller number from the bigger one. In this case, the equation is 12 2/4 - 10 1/4.
Let us set aside the fraction and subtract 10 from 12 first.
12 - 10 = 2
Therefore, the whole number of the difference will be 2.
Let's solve for the fraction now.
2/4 - 1/4 = 1/4
Therefore, the fraction in the answer will be 1/4.
Add 2 and 1/4 to get 2 1/4, which is the answer.

Answer:
a. .
b. The axis of symmetry for is .
Step-by-step explanation:
a. The vertex form of a quadratic is given by , where (h, k) is the vertex.
To convert from form to vertex form you use the process of completing the square.
Step 1: Write in the form . Add and subtract 4:
Step 2: Complete the square
b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
For a quadratic function in standard form, , the axis of symmetry is .
The axis of symmetry for is .
Look at the graph shown below.
