Answer:
y=x^2+2
Step-by-step explanation:
Quadratic function has a general function:
And you can calculate the axis of symmetry with:
x1=-b/2a
Then you calculate the axis for each equation:
1. y = x^2 + 2x
x1=-2/(2*1)=-1
2. y = x^2 − 16x + 58
x1=-(-16)/(2*1)=8
3. y = x^2 + 2
<em>notice: you don't have b term</em>
x1=-0/(2*1)=0
4. y = x ^2 − 4x + 2
x1=-(-4)/(2*1)=2
Answer: Use Fractions and Multiplication.
Step-by-step explanation:
To start, you need to find 1/6 of 12. The easiest way to do this is to multiply 12/1 by 1/6. The answer is 12/6, which simplifies to 2. Then, you do the same for 2/3: 12/1*2/3=24/3, which simplifies to 8. You then add the results to figure out how much has been eaten. 8+2=10
Answer:
d = -1/3, 0
Step-by-step explanation:
Subtract the constant on the left, take the square root, and solve from there.
(6d +1)^2 + 12 = 13 . . . . given
(6d +1)^2 = 1 . . . . . . . . . .subtract 12
6d +1 = ±√1 . . . . . . . . . . take the square root
6d = -1 ±1 . . . . . . . . . . . .subtract 1
d = (-1 ±1)/6 . . . . . . . . . . divide by 6
d = -1/3, 0
_____
Using a graphing calculator, it is often convenient to write the function so the solutions are at x-intercepts. Here, we can do that by subtracting 13 from both sides:
f(x) = (6x+1)^ +12 -13
We want to solve this for f(x)=0. The solutions are -1/3 and 0, as above.
