If the value of x is 5, then the value of f(x) will be 9. Then the correct option is C.
The missing problem is attached below.
<h3>What is a function?</h3>A statement, principle, or policy that creates the link between two variables is known as a function.
The function is given below.
f(x) = x + 4
If the value of x is 5, then the value of f(x) will be
f(5) = 5 + 4
f(5) = 9
Then the correct option is C.

Answer:
y = - 3x - 3
Step-by-step explanation:
the equation of a linear function in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table
m = =
= - 3
y = - 3x + b ← is the partial equation
To find b substitute any other point from the table into the partial equation
using (2, - 9), then
- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3
y = - 3x - 3 ← linear relationship
