What is the justification for each step in the solution of the equation 3(2x + 7) - 4 = 53 - 3x?

DerKrebs [107]

Step 1 3(2x+7)-4=53-3x given
step 2 6x+21-4=53-3x expanding
step 3 6x+17=53-3x adding (21-4)
step 4 9x+17=53 adding 3x to both parts
step 5 9x=36 subtracting 17 from both sides
step 6 x=4 divding by 9

Which is the graph of the function: f(x) = x2 - 4x + 3

Nina [5.8K]

Answer:

Option 1

Step-by-step explanation:

To find the graph of the quadratic function, we find it's zeros.

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}$

$\Delta = b^{2} - 4ac$

f(x) = x² - 4x + 3

This means that $a = 1, b = -4, c = 3$

$\Delta = b^{2} - 4ac = (-4)^2 - 4(1)(3) = 16 - 12 = 4$

$x_{1} = \frac{-(-4) + \sqrt{4}}{2} = 3$

$x_{2} = \frac{-(-4) - \sqrt{4}}{2} = 1$

Zeros at x = 1 and x = 3, that is, it crosses the x-axis at this values, so the graph is given by option 1.
