What effect does the "a" value have on the function f(x)=log(x)

Mathematics
1 answer:
Leni [432]3 years ago

I would guess they're referring to some general form first<span>f(x)=alog(x−h)+k</span>Where 'h' represents horizontal shifts, 'k' vertical shifts and 'a' stretches the function. "a" will also reflect the function across the x-axis if the value is negative. But NOT across the y-axis. I hope that's the place they wanted to put the a at least

Answer:

x = -1  and  x = -9

Step-by-step explanation:

Once again, we have a problem with the |x| in it, so like last time, every number that is the outcome within those brackets, is positive.

Let us check:

A. x = 21 over 4 and x = -11 over 4

This one is a very simple to say no to, as we are talking about decimals (if you convert into decimals at this point), as in -16 there are no decimals.

False.

B. x = -1 and x = 9

-1 is correct. But 9 is not. Why? Here:

9 + 5 is 14

14 the multiplied by -4 does not equal -16

False.

C. x = -1 and x = -9

Like what I said before, -1 is  correct, now in this answer, -9 is also correct.

Unlike the last one, this one is -9 + 5 which is -4, then since it is inside the positive brackets, the number 4 becomes positive.

4 * -4 = -16

True.

The last one is incorrect. You know why

Solve for x: 18 over 10= x over 12 Prove your answer in the show your work box.<br> Pls hurry
alexandr1967 [171]

i'm doing cross-multiplication for this problem:

\frac{18}{10}=\frac{x}{12}     multiply 18 · 12, which is 216

\frac{216}{10}=x     divide 216 ÷ 10, which is 21.6

21.6 = x, is the final answer

I really need help on this can someone help me please!!!!
Nikitich [7]
It is rational and equal to 0. square root of 28 simplifies to 2 root 7, because you can take out the 4 and leave the 7 under the radical. because sq rt of 28 is 2 root 7, it's the same as the first term so it equals 0

Apply the distributive property to factor out the greatest common factor.<br> 56<br> +<br> 32<br> =
valentina_108 [34]

Answer:

8 * (7 + 4)

See process below

Step-by-step explanation:

We start by writing each number in PRIME factor form:

56 = 2 * 2 * 2 * 7

32 = 2 * 2 * 2 * 2 * 2

Notice that the factors that are common to BOTH numbers are 2 * 2 * 2 (the product of three factors of 2).Therefore we see that the greatest common factor for the given numbers is : 2 * 2 * 2 = 8

Using this, we can write the two numbers as the product of this common factor (8) times the factors that are left on each:

56 = 8 * 7

32 = 8 * 2 * 2 = 8 * 4

We can then use distributive property to "extract" that common factor (8) from the given addition as shown below:

56 + 32

8 * 7 + 8 * 4

8 * (7 + 4)

8 * (11)
