F(x) = 6x – 12 ; shifts 4 units down.

f(x) = 6x-16

Step-by-step explanation:

Since the function is shifting 4 units down, it will be moving down the y axis, meaning the y-intercept will decrease by 4.

y=mx+b is the formula for the straight line, where b is the y-intercept. The y-intercept in this function is -12, so we would just subtract -4 from -12 to get our answer.

-12-4=-16

Make sure to leave the coefficient of x

Therefore, f(x) = 6x-16

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
