Which graph represents the function f(x) = 2 x – 1 + 2?

Mathematics

tatuchka [14]3 years ago

Answer:

The graph is positive and would have a y intercept of 1 and a slope of 2 which means choose a point on the graph and add 2 to the y and 1 to the x and you should be at the next point on the line.

Step-by-step explanation:

y=mx+b

f(x)=y

m = slope

b = y intercept

First you need to make it look like y=mx+b

y = 2x - 1 + 2

y = 2x + 1

Now we can say,

m = 2

b = 1

or,

Slope = \frac{2}{1}

y intercept = 1

Slope (m) = \frac{rise}{run}

So the numerator is the value your are going to go up or down along the graph and the denominator is the value of how far you are going to go left or right along the graph. If the slope is positive then the graph is inclining. If the slope is negative, the graph is declining.

Tom and same sit down to eat a pie. Tom eats 2/3 of the pie , and sam eats 1/4 of the pie what function of the pie is left
dlinn [17]

If you mean fraction,

Tom: 2/3

Sam: 1/4

Now we change the denominator.

Tom: 6/12

Sam: 3/12

6/12 + 3/12 = 9/12

9/12 can be simplified, so 3/4 of the pie was eaten.

4/4 - 3/4 = 1/4

The answer is 1/4.
