Question

The table shows the inputs and outputs for the function f (x) = -7x-5.Input-10-5O5Output65?-5-40What is the output value of the function when the input is –5?403050

Answer 1

30

Step-by-step explanation:

To know the output value of the function, we need to replace x by -5 and calculated f(x). So:

`\begin{gathered} f(x)=-7x-5 \\ f(-5)=-7(-5)-5 \\ f(-5)=35-5 \\ f(-5)=30 \end{gathered}`

Therefore, if the input x is -5, the output f(x) is 30

So, the answer is 30.
