Question

Consider the function:

f(x) = 2x - 1, where f(-3) = __?
a) 4
b) 2
c) -7
d) -5

Answer 1

The value of f(-3) is -7.

The answer is option ⇒C

Step-by-step explanation:

To find the value of f(-3) using the function f(x) = 2x - 1, we substitute -3 into the equation:

f(-3) = 2(-3) - 1

= -6 - 1

= -7

Therefore, f(-3) = -7.

In this calculation, we replace every occurrence of x in the function f(x) = 2x - 1 with -3. By simplifying the expression, we find that f(-3) is equal to -7. This means that when we input -3 into the function, the output value is -7.

The answer is option ⇒C
