Isuck at this stuff (fast)

use the graph of ƒ to find where ƒ(x) > 0. assume the entire function is graphed.

[–1, –8)

[–1, 0)

(–1, 0)

(–1, 0]

[-1,0)

Step-by-step explanation:

f(x) > 0 is where the function is above the x-axis or when y > 0. So lookign at the graph, the function is above the x-axis between x values -1 and 0. You can write this as an interval [-1,0). You use a bracket on the left since it is above 0 and a parenthesis on the right since it has already reached 0.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
