Does anyone know a rule that work for all of these

Oxana [17]

Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}

This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2

However we must double the values to get back to the original list. So the rule is y = 2*x^2

Which expression is equivalent to log3(x + 4)?

solmaris [256]

ANSWER

The third option is the correct answer

$log3(x + 4) = log(3) + log(x + 4)$

EXPLANATION

The expression given to us is

$log3(x + 4) = log(3) + log(x + 4)$

This logarithmic expression is of the form

$log(A \times B)$

So we use the multiplication law of logarithm which is given by

$log(A \times B) = log( A ) + log( B )$

We therefore set

$A = 3$

$B = x + 4$

The given expression now becomes,

$log3(x + 4) = log(3) + log(x + 4)$
