F(x)=3x+4. determine the value of f (x) when x equals -1

ANSWER

The value of this function at x=-1 is 1

EXPLANATION

The given function is

We want to find the value of this function at x=-1.

We substitute x=-1 into the function to obtain:

We multiply out to obtain:

Therefore the value of this function at x=-1 is 1.

Step-by-step explanation:

Given the linear function f(x):

By definition. a relation is a function if each input value has only one output value. In this case you need to find the output value for the input value . In order to do this, you need to substitute this value of the variable "x" into the linear function given.

Then:

When :

Remember the multiplication of signs:

Then, the value of f(x) when is:

answer: 4 (:
