Here is your function:

[tex]f(x)=2x+2[/tex]

You're looking for f(-1). To get your answer, you have to replace all the x's with -1.

Here is your new equation:

[tex]f(-1) = 2(-1)+2[/tex]

Multiply 2 by -1

[tex]2 \times -1 = -2[/tex]

Remember:

MULTIPLYING

  • Positive(+) times negative(-) is equal to negative
  • Positive(+) times positive(+) is equal to positive
  • Negative(-) times negative(-) is equal to positive
  • Negative(-) times positive(+) is equal to negative

DIVIDING

  • Positive(+) divided by positive(+) is equal to positive
  • Positive(+) divided by negative(-) is equal to negative
  • Negative(-) divided by positive(+) is equal to negative
  • Negative(-) divided by negative(-0 is equal to positive

Since you're multiplying a negative number by a positive number, the answer will be negative.

Here is your new equation:

[tex]f(-1) = -2+2[/tex]

Add -2 and 2:

[tex]-2+2 = 0[/tex]

That means your answer is 0

[tex]f(-1)=0[/tex]
