Consider the function f(x) = 2x−1

Question

What is the output if the input is x=−3
?

(1 point)
f(x)=

Answer 1

f(x) = 2(-3) - 1
f(x) = -6 - 1
f(x) = -7

Therefore, the output is -7 when the input x = -3.

Answer 3

Let's plug in the values of each ordered pair into the equation and see which one satisfies it.

For the ordered pairs:

1. (6, -1):
y = (2/3)(6) - 5
y = 4 - 5
y = -1

2. (-3, 7):
y = (2/3)(-3) - 5
y = -2 - 5
y = -7

3. (3, 3):
y = (2/3)(3) - 5
y = 2 - 5
y = -3

4. (9, 2):
y = (2/3)(9) - 5
y = 6 - 5
y = 1

Therefore, the ordered pair (6, -1) satisfies the relation y = 2/3x - 5.
