How does the graph of g(x) = (x + 4)^3 − 6 compare to the parent function f(x) = x^3?
ANTONII [103]

Answer:

  D) g(x) is shifted 4 units to the left and 6 units down

Step-by-step explanation:

When -6 is added to the y-value, it moves the point on the graph down 6 units. Compared to f(x), g(x) is 6 units down.

Transforming the function using f(x -h) shifts its graph h units to the right. Here, we have h=-4, so the graph is shifted 4 units to the left.

Show all work to factor x^4-10x^2+9 completely
dimaraw [331]

Answer:

(x^{2}-9)(x^{2} -1)

Step-by-step explanation:

Step 1: Find what adds to _ and multiples to_

It needs to multiple to the 'c' term or 9

It needs to add to the 'b' term or -10

Step 2: Find the numbers

We know -9 and -1 make 10 and multiple to 9

-9 x -1 = 9

-9 + (-1) + -10

Step 3: Write equation in form a(x-r)(x-s)

a = 1

r = -9

s = -1

Plug in the equation to get the factored form of the equation:

(x^{2}-9)(x^{2} -1)

Therefore the factored form of the equation is (x^{2}-9)(x^{2} -1)
