Why is the value of a-1 always less than the value of a.

2 answers:

<span>The - before the 1 represents it is less, so the -1 will always be less than a, since the - is before the one, and so that means the 1 is less than a.</span>

-1 means to subtract 1, therefor whatever number you pick for a you subtract 1 therefore a will always be more

Match the three graphs to the function they represent ?

Mama L [17]

Suppose that a>b>1, then

$a^x>b^x$ and $\log_ax$

Therefore, since 2<3<7, $\log_2x>\log_3x>\log_7x.$

Choose an arbitrary x>1. You have that a takes the greatest values at x, c takes the smallest value at x. Thus,

a>b>c and

$a=\log_2x;$
$b=\log_3x;$
$c=\log_7x.$

Answer: correct option is B.
