Question

F(x) = -3x + 2 for x =3

Answer 1

Answer:

x = -7

Step-by-step explanation:

f(x) = -3x + 2

= -3(3) + 2

= -9 + 2

= -7

Answer 2

Solution:

we have input x= 3

and function f(x)= -3x+2

putting x=3 into f(x), we have,

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

= -9+2

= -7

we can show input x and output f(x) as ordered pair, and it is given by.

let there be a set of input given by-

I= {3}

and for output-

O= {-7}

for ordered pair we will find I×O, that is now,

{(3,-7)}

which is not same as O×I

Hence, ordered pair is {(3,-7)}
