What is the value of f(-1) when f(x)=2x+2? F(-1)=?
igomit [66]

Here is your function:

f(x)=2x+2

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:

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

Multiply 2 by -1

2 \times -1 = -2

<em>Remember:</em>

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:

f(-1) = -2+2

Add -2 and 2:

-2+2 = 0

That means your answer is 0

        ↓

f(-1)=0

The points (4,t) and (5,
aleksley [76]

Answer:

-3

Step-by-step explanation:

Here is a different example.

'm' is the gradient (or slope). We measure the difference between the two x values and two y values to see how each of them changed respectively. We know m = rise/run so we can put in our slope (7) and points to find t.

If charlene brewster has times of 8.4, 8.6, 8.3, 8.5, 8.7 ans 8.5 and a performance rating of 110% percent, what is the normal t
yanalaym [24]
<span>First we define Charlene's the average time, which is (8.4 + 8.6 + 8.3 + 8.5 + 8.7 + 8.5)/6 = 8.5. Normal time is 8.5/1.1 = 7.7. Charlene is faster than normal.</span>
