PLS HELP

Let function ƒ be defined as: ƒx = 7x − 2. What does ƒ(4m) evaluate to?

Select one:
a.
26
b.
26m
c.
28m – 2
d.
28mx – 2

Answer 1

To find ƒ(4m) for the function ƒ defined as ƒx = 7x − 2, you replace x with 4m and simplify to get 28m − 2, which is option c.

Step-by-step explanation:

The question asks what the function ƒ(4m) evaluates to if the function ƒ is defined as ƒx = 7x − 2. To solve this, we simply substitute 4m for x in the function's formula.

ƒ(4m) = 7(4m) − 2

By applying the distributive property, we multiply 7 by 4m:

ƒ(4m) = (7 × 4m) − 2

ƒ(4m) = 28m − 2

Therefore, the correct answer is 28m − 2, which corresponds to option c. This demonstrates how to apply the concept of function evaluation, using algebraic manipulation to replace the function's variable with a given expression and simplify.
