If f(x)=4x^2-6

find all x such that f(x)= 106

Step-by-step explanation:

So we have the function:

And we want to find all x such that f(x) is 106. So, substitute 106 for f(x):

Add 6 to both sides:

Divide both sides by 4:

Take the square root of both sides:

Simplify the square root:

So, those are the two values that will satisfy our requirement.

And we're done!
