Answer:

k determines how many units up or down the parent function will be translated.

Step-by-step explanation:

y=f(x)+k, where k>0 ——> the parent function will be translated up k units

y=f(x)+k, where k<0 ——> the parent function will be translated down k units

Prove triangle AOC is congruent to triangle BOD

marta [7]

Step-by-step explanation:

We are given two Triangles and we need to prove them congruent . In ∆AOC and ∆BOD , we have

$\to AC = BD ( given ) \\\\\to OD = OA \\\\\to \angle CAO =\angle BDO (Since\ BD || AC )$

Therefore by AAS congruent condition we can say that ,

$\implies\red{ \triangle AOC \cong \triangle BOD }$

Hence Proved!

Write the polynomial as a product of linear factors, x^4-5x^2-36

Lerok [7]

9514 1404 393

Answer:

(x +3)(x -3)(x +2i)(x -2i)

Step-by-step explanation:

The factoring to quadratics makes use of the fact that -36 = (-9)(4).

x^4 -5x^2 -36

= x^4 -9x^2 +4x^2 -36

= x^2(x^2 -9) +4(x^2 -9)

= (x^2 +4)(x^2 -9)

The form for factoring the difference of squares comes into play here. Of course -4 = (2i)^2.

= (x^2 -(2i)^2)(x^2 -3^2)

= (x -2i)(x +2i)(x -3)(x +3) . . . factored to linear terms
