Add these polynomials and simplify. Enter your response in standers form (x^4-9+5x^7) + ( 5x -10 +3x^4 - 2x^2)
Natali [406]

Answer:

5x^7 + 4x^4 - 2x^2 + 5x - 19

Step-by-step explanation:

Start by copying 5x -10 +3x^4 - 2x^2 here.  Next, add x^4 to +3x^4, -9 to -10, and 5x^7:

5x - 10 +3x^4 - 2x^2

     -  9  +x^4               + 5x^7

-----------------------------------------

5x - 19 + 4x^4 - 2x^2 + 5x^7

Now rearrange these terms in descending order by powers of x:

5x^7 + 4x^4 - 2x^2 + 5x - 19   (answer)

Identify the parent function that can be used to graph the function f(x)= (1/4 x)^3
Kaylis [27]

Answer:

f(x)=x^3

Step-by-step explanation:

The parent function denotes the simplest function (free from any horizontal/vertical stretch/compression) that represents a family of functions. In this case the term 1/4 indicates a horizontal stretch and should be removed to find the parent function of f(x)=x^3. From here we're in simplest form, since y=x or others represent a completely different family of functions and cannot be obtained from horizontal/vertical stretches/compressions.
