Question

What is the value f(-5) for the function f(x) = 5x - 3?

Answer 1

-28

Explanation:

Simply plug -5 in for x in the given equation

f(-5) = 5(-5) - 3

f(-5) = -25 - 3

f(-5) -28

Answer 2

`\sf \: f( - 5) = - 28`

Explanation:

Now we have to,

→ Find the required value of f(-5).

The function is,

→ f(x) = 5x - 3

Then the value of f(-5) will be,

→ f(x) = 5x - 3

→ f(-5) = 5(-5) - 3

→ f(-5) = -(5 × 5) - 3

→ f(-5) = -25 - 3

→ [ f(-5) = -28 ]

Hence, the value of f(-5) is -28.
