Respuesta :

(f + g) (x)= -3 x+ 5

(f + g)(x) = -3x + 5

What is function?

  • "It defines a relation between input and output values."
  • "In function, for each input there is exactly one output."

For given question,

We have been given two functions.

f(x) = x+8 and g(x) = -4x - 3

We need to find the value of (f + g)(x)

This means, we need to find the addition of functions f(x) and g(x)

⇒ (f + g)(x) = f(x) + g(x)

⇒ (f + g)(x) = (x + 8) + (-4x - 3)

⇒ (f + g)(x) = x - 4x + 8 -3

⇒ (f + g)(x) = -3x + 5

Therefore, (f + g)(x) = -3x + 5
