How would you write the equation for the square root function below? Vertical stretch by a scale factor of 3.
Reflect across the x-axis.
Vertical shift down 4 units.

a = 11 : 4

b = 38

c = 1 for every 6

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
