If k(x) = x^2 and p(x) = k(x) + n, what is the value of n?
kodGreya [7K]

Answer:

The value of n is -6

Step-by-step explanation:

  • If the function f(x) is translated k units up, then its image is g(x) = f(x) + k
  • If the function f(x) is translated k units down, then its image is g(x) = f(x) - k
  • The vertex form of the quadratic function is f(x) = a(x - h)² + k, where a is the coefficient of x² and (h, k) is the vertex

∵ k(x) = x²

→ Its graph is a parabola with vertex (0, 0)

∴ The vertex of the prabola which represents it is (0, 0)

∵ The given graph is the graph of p(x)

∵ Its vertex is (0, -6)

∴ h = 0 and k = -6

∵ a = 1

→ Substitute them in the form above

∴ p(x) = 1(x - 0)² + -6

∴ p(x) = x² - 6

→ Substitute x² by k(x)

∴ p(x) = k(x) - 6

∵ p(x) = k(x) + n

→ By comparing the two right sides

∴ n = -6

∴ The value of n is -6

Look at the attached figure for more understanding

The red parabola represents k(x)

The blue parabola represents p(x)

Please explain how this digraph works.
dusya [7]

Angles XQL and MQR are congruent because they are vertical angles. So

209 - 13 <em>b</em> = 146 - 4 <em>b</em>

Solve for <em>b</em> :

209 - 13 <em>b</em> = 146 - 4 <em>b</em>

209 - 146 = 13 <em>b</em> - 4<em> b</em>

63 = 9 <em>b</em>

<em>b</em> = 63/9 = 7

Then the measure of angle XQL is

(209 - 13*7)º = 118º

Find the slope of (-9,18),(-13,5)
Jet001 [13]

Answer:

3.25

Step-by-step explanation:

The slope formula is slope = y2 - y1 / x2 - x1 and the variables are found by assigning them with their corresponding values. Here, x1 = -9, x2 = -13, y1 = 18, and y2 = 5. Next, substitute these values in and get 5 - 18 / -13 - (-9). This can fully simplify to 13 / 4 or 3.25.
