The answer is the letter b cos u = 1 /sec u

When you use it in the left side of the identity that you want to verify, sec y cos y = 1 , you get this:

sec y cos y = 1

[sec y ] [ 1 / sec y ] = 1

[sec y] / [sec y] = 1

1 = 1 which proves the idenity.

The f(x) notation means that were ever you see n x on the right you put the value of x.

The question is which point has x = - 3 and what is the associated y value?

You could do it this way, just so you understand it.

QF Q7.) Use properties of logarithms to expand the logarithmic expression as much as possible. Evaluate logarithmic expressions

Softa [21]

Attached is the solution.
The following log properties are used:
$log(x^n) = nlog(x)$
$log(\frac{a}{b}) = log(a) - log(b) \\ \\ log(ab) = log(a) + log(b) \\ \\ log_9 (81) = 2 \rightarrow 9^2 = 81$

The absolute value of y is further from 0.

Explanation:
The absolute value of any number is a positive. If the value of y is greater than x, then y would be further. Let’s input a number as an example. Let’s say that the absolute value of y was 9 and the absolute value of x is 4 due to the y value being larger. 4 is closer to 0 compared to 9 so the absolute value of y is further from 0.
