Answer:
Domain: (-infinity, +infinity) since you can pick any x values.
Range: [0, +infinity) since it does not go below the x axis.
Step-by-step explanation:
The graph is a parabola given by 
lets pick a few x values:
x = 1 gives us y = 1^2, which = 1
x = -1 gives us y = (-1)^2, which = 1
The parabola's domain is any x value as it extends to infinity.
For its range, you can see that it does not go below the x axis at x = 0. Therefore, the range of the parabola is from [0, infinity]
X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
Answer:
3. Quadratic
Step-by-step explanation:
Penny is falling under gravity
acceleration due to gravity is constant
Velocity is the integral of acceleration, which is linear
Displacement is the integral of velocity, which is quadratic
Answer:

<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(6x² - 4x + 2) - (-2x² + 3x - 5)
<u>Step 2: Simplify</u>
- Distribute negative: 6x² - 4x + 2 + 2x² - 3x + 5
- Combine like terms (x²): 8x² - 4x + 2 - 3x + 5
- Combine like terms (x): 8x² - 7x + 2 + 5
- Combine like terms (Z): 8x² - 7x + 7
