Answer:

f(x)= -2x + 1

Step-by-step explanation:

The function we will find is to be written in slope-intercept form, which is y=mx+b.

One way to find the answer would be by graphing the function, wich you can do on an online calculator or a sheet of paper.

Another way to get to our answer without even having to graph is by finding the y-intercept, or the b, of the function given in the table.

We can do this by looking at the 0 value of the table. The table tells us that the y-intercept is 1.

So, we have to look at our options and see which one has +1 for the y-intercept.

The option f(x)=-2x+1 is the answer

How to check your work: input the given x values into the chosen function, in this case f(x)= -2x + 1

So for example, you could check that this answer is the function by doing

  • f(-1) = -2(-1) + 1
  • f(-1) = 2 + 1
  • f(-1) = 3

Make sure to do this to all values.

Hope this helps!

The answer is A, you would plug in 3 for fx so therefore the answer would be A. Then to make sure plug in the other functions.:)

Lubov Fominskaja [6]
F(5) = 5² +4*5=25+20 = 45
g(6) = 2*6 +2 =12+2=14

f(5) + g(6)
= 45 +14 =59

4X + 8 < 1 + ( 2X - 5) PLEASE EXPLAIN
Simora [160]

Answer:

x < - 6

Step-by-step explanation:

Given

4x + 8 < 1 +(2x - 5) ← remove parenthesis

4x + 8 < 1 + 2x - 5, that is

4x + 8 < 2x - 4 ( subtract 2x from both sides )

2x + 8 < - 4 ( subtract 8 from both sides )

2x < - 12 ( divide both sides by 2 )

x < - 6

What is -5g + ( -17fg ) =
Anika [276]

Hello from MrBillDoesMath!

Answer:

-g (5 + 17f)    



Discussion:

The terms only have the factor "g" in common so


-5g + ( -17fg) =                       => factor "g" from each term

g ( -5 - 17f) =

-g (5 + 17f)    

is as much as it can be factored.


Thank you,

MrB
