F(x)= {x+4 if x<5

Mathematics
1 answer:
mart [117]2 years ago

Answer:

  A.  f(0) = 4

  B.  f(6) = 8

Step-by-step explanation:

When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.

<h3>A.</h3>

x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.

  f(0) = 0 +4 = 4

__

<h3>B.</h3>

x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.

  f(6) = 8

Romashka [77]

Answer:

A and D have whole grid squares that are the same size and aren't over lapping

C has overlapping grid squares making it hard to count

B can't be used to find area because some of the grid squares are different sizes

You still could use B because four of the smaller squares seems to be equivalent to one of the larger squares

8.1 and 11.4, okay!

8.1 x 11.4 = 92.34

This means that there are two triangles we just measured, so its still 92.34. There are five sides including the one we just used. This means that the total area should be 461.7!

(MODERATORS, I ACCIDENTALLY PASTED SOMETHING THAT ISN'T IN HERE ANYMORE, DO NOT DELETE THIS PLEASE.)
