Determine which ordered pairs fall on the graph of f(x) = -2x-1
Pavlova-9 [17]

Answer:

No order Pair fall on the graph

Step-by-step explanation:

The given Function is

f(x)= -2x -1       ...............(i)

Now to see whether these ordered pairs Lay on it we will put each ordered pair in the equation (i)


Lets take first ordered pair (1,1)

here x = 1

putting it in (i) gives

f(1)= -2(1) -1

f(1)= -3

this is not equal to 1 so the order pair (1,1) does not fall on function f(x)= -2x -1

Lets take second ordered pair (-1,-4)

here x = -1

putting it in (i) gives

f(-1)= -2(-1) -1

f(-1)= 1

this is not equal to -4 so the order pair (-1,4) does not fall on function f(x)= -2x -1


Lets take third ordered pair (-2,-1/8)

here x = -2

putting it in (i) gives

f(-2)= -2(-2) -1

f(-2)= 3

this is not equal to -1/8 so the order pair (-2,1/8) does not fall on function f(x)= -2x -1


Lets take fourth ordered pair (0,-1/2)

here x = 0

putting it in (i) gives

f(0)= -2(0) -1

f(0)= -1

this is not equal to -1/2 so the order pair (0,-1/2) does not fall on function f(x)= -2x -1

Solve for x:<br> 3x^2-5x=2
Yanka [14]
3{ x }^{ 2 }-5x=2\\ \\ 3{ x }^{ 2 }-5x-2=0\\ \\ \left( 3x+1 \right) \left( x-2 \right) =0\\ \\ \therefore \quad x=2\\ \\ \therefore \quad x=-\frac { 1 }{ 3 }
