The function f(x) = x^3 is transformed to f(x) = 4x^3. Which statement describes the graph of the transformed function?
Natalka [10]

Answer: Option D.

Step-by-step explanation:

The translation is defined as

g(x)=kf(x)

Where, k is stretch factor.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

It is given that,

f(x)=x^3

After transformation the function becomes

f(x)=4x^3

here, k=4>1, so the graph was stretched vertically by a factor of 4.

Therefore, the correct option is D.

Remove parentheses and simplify 7a+6b-4 (3a-3b)
Varvara68 [4.7K]
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion

7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)

7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
