Answer:

$\lim_{x\to 3^-} f(x)=-1$

Step-by-step explanation:

We have a piesewise function composed of three pieces. two line segments and one point.

The first line cuts at point (0,0) and ends at point (3, -1)

If we use these two points we can find the equation of the line.

The slope m is:

$m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-1 - (0)}{3-0}\\\\m = -\frac{1}{3}$

So the equation is:

$y = -\frac{1}{3}x + b$

As the line cuts in (0,0) then $b = 0$ and the equation is:

$y = -\frac{1}{3}x$

The equation of the second line is:

$y = -4$

Now we can find f(x) (although it is not necessary to find the equation of f(x) because we have its graph)

$f(x) = -\frac{1}{3}x$ if $x$ ; $f(x)=-4$ if $x> 3$ ; $f(x)= 7$ if $x = 3$ .

The limit of f(x) when x tends to 3 from the left $\lim_{x\to 3^-} f(x)$ is the limit of the function when x approaches 3 from the left. If x approaches 3 from the left then $x$ . If $x$ then f(x) is given by the line $y = -\frac{1}{3}x$ . Then the limit is -1 as seen in the graph

Question 4 (Multiple Choice Worth 1 points)

shutvik [7]

The right answer for the question that is being asked and shown above is that: "d.8 open parentheses x plus 4 close parentheses over quantity x minus 6" The simplified that completely quantity 8 x minus 56 over quantity x squared minus 49 divided by quantity x minus 6 over quantity x squared plus 11 x plus 28 is that 8 open parentheses x plus 4 close parentheses over quantity x minus 6

The value of the function y= (3/5)t decrease by what percentage of t increases by 1 unit

kirza4 [7]

Answer:

Percent of decrease in the value is 40%.

Step-by-step explanation:

Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.

When t=1

y= $\frac{3}{5}^{1}$ =0.6
