What is the function of the graph?

Answer:

A.f(x)=ln(−x)

Step-by-step explanation:

<u>Graph Of The Logarithm Function</u>

The domain of the logarithm function, written as y=log(u), is u>0. This means that it doesn't exist for any value of u less than or equal to zero

We can see in the graph the function is defined for all negative values of x. It means that if we choose any of the points in the graphs, the selected function must exist at that point.

Let's pick the point (-7,2). If we set x=-7 in the second option B, it would produce log(-5) which is not defined. A similar thing happens when using the third function to produce ln(-8) who doesn't exist either. The function D is not good because it would take log(-7). The only possible function is the first one f(x)=ln(-x), when evaluating f(-7)=ln7=1.95

What steps do you use to solve y=x+12 and y=-x+17 an unknown number y is 12 more than an u known number x the number y is also x

Tamiku [17]

Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

$x+12=17-x$

Add x to both sides to remove the negative x on the right side of the equation:

$2x+12=17$

Subtract 12 from both sides to remove the 12 on the left side of the equation:

$2x=5$

Divide both sides by 2 to cancel out the x coefficient

$x=2.5$

jolli1 [7]

Answer:

d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.

Step-by-step explanation:

Confidence interval of a proportion p.

We build a confidence interval at the x% level from a sample.

With this, we can say that we are x% sure that the true population propotion is in the interval.

The 95% confidence interval is (0.53, 0.59).

This means that we are 95% sure that the true population proportion is between 0.53 and 0.59.

So the correct answer is:

d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
