How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?

Anastasy [175]

Whenever you can invert a function, you have that the graphs of $f(x)$ and its inverse $f^{-1}(x)$ are reflected with respect to the line $y=x$

So, given any point on the graph of $f^{-1}(x)$ , you can simply swap its coordinates to get the correspondent point on the original function $f(x)$

As an example, all exponential functions pass through the point $(0,1)$ , while all the logarithmic functions pass through the point $(1,0)$

Question 28 (1 point)

aniked [119]

Answer:

+ 16

Step-by-step explanation:

x² - 8x = - 10

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + (- 4) = - 10 + (- 4)²

x² - 8x + 16 = - 10 + 16

thus 16 is added to both sides to complete the square

It is 9 because you have a 30,60,90 triangle, and then you can use pythagorean theorem.

Multiply: 2.7 × (–3) × (–1.2). A. –9.72 B. –10.8 C. 10.8 D. 9.72

Vikentia [17]

Answer: $\text{ D) } 9.72$

Step-by-step explanation:

Here the give expression is,

$2.7 \times(-3)\times (-1.2)$

We can write,

$2.7 \times(-3)\times (-1.2) = 2.7 \times 3.6$ ( because $-a\times -b = ab$ )

$2.7 \times(-3)\times (-1.2) = 9.72$

⇒ Option D is correct.
