Question

If R(x) = 2 – 3x – 1, find R(-2)

a. -3
b. 9
c. -9
d. -11

PLEASE HELP

Answer 1

Answer:

C

Step-by-step explanation:

C

Answer 2

The output of  $R(x) = x^{2} - 3x- 1$ when x = -2 is 9.

What is PEMDAS?

PEMDAS exists as an acronym for the terms parenthesis, exponents, multiplication, division, addition, and subtraction.

To estimate the value of R(-2)

Substitute the value of x = -2, then

$R(-2) = (-2)^{2} - 3(-2) - 1$

By using the PEMDAS order of operations

Calculate exponents, $(-2)^2 = 4$

= 4 - 3(-2) - 1

Multiply and divide (left to right), 3(-2) = -6

= 4 - (-6) - 1

Add and subtract (left to right),

4 - (-6) - 1 = 9

Therefore, the value of R(-2) = 9.
