Given the function f (x) = V6x - 3, what is the value of x when f (x) = 21?

Hope this helps

Step-by-step explanation:

21v^6-3

also ^ that mean exponent  

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
