The graph of a function f is shown below. Find f (2)

liberstina [14]

Answer: f(2) is 3.

Step-by-step explanation:

f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

======

[One could also determine the equation for the line. Provided below.]

The slope is -(1/2) and the y-intercept is 4:

y = -(1/2)x + 4

For x=2,

y = -(1/2)*(2) + 4

y = 3

y(2) = 3

An oven heating element turns on when the internal temperature falls to 20 degrees below the set temperature and turns off when

son4ous [18]

Answer:

The range of the oven is $385\leq T\leq 410$

Step-by-step explanation:

Consider the provided information.

The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature.

You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405.

The internal temperature falls to 20 degrees, therefore the lowest set can be:

405-20=385 degree.

The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.

Hence, the temperature will be lying between 385 degree and 410 degree.

This can be written as: $385\leq T\leq 410$

Hence, the range of the oven is $385\leq T\leq 410$

I NEED HELP!!! ASAP!!!

omeli [17]

Answer:

Step-by-step explanation:

In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D

It isn't a gradual line, as 6x is, so that is eliminated.

When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
