Question

How do you calculate f(-1.60) if f is the function given by the formula `f(x) = -1.4x + -9.1`?

Answer 1

`f(-1.60)=-6.86`

Explanation:

To solve this, simply substitute `-1.60` into `x`.

`f(x)=−1.4x−9.1`
`f(-1.60)=−1.4(-1.60)−9.1`
`f(-1.60)=−1.4(-1.60)−9.1`
`f(-1.60)=2.24−9.1`
`color(red)(f(-1.60)=-6.86`
