The coordinate of the function f(x) = x + 1 at x = 4, will be (4, 5).
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function f(x) is given below.
[tex]\rm f(x) = \dfrac{x^2-3x-4}{x -4}[/tex]
Then the factor of the numerator, then we have
⇒ x² - 3x - 4
⇒ x² - 4x + x - 4
⇒ x(x - 4) + 1 (x - 4)
⇒ (x - 4)(x + 1)
Then the function will be
[tex]\rm f(x) = \dfrac{(x- 4)(x + 1)}{x -4}[/tex]
Simplify the function, then we have
f(x) = x + 1
The above function is a linear function.
At x = 4, the coordinate of the function will be
f(4) = 4 + 1
f(4) = 5
Then the coordinate of the function f(x) = x + 1 at x = 4, will be (4, 5).
