Question

Algebra can you solve this function f(x)=0.28x+1.7 to find the rate of change?

Answer 1

`color(blue)(0.28)`

Explanation:

The rate of change of a function at a specific point is the gradient at that point.

This is a linear function, so it has a constant rate of change.

If we have a function of the form:

`f(x)=mx+b`

Then:

`m="gradient"` and this is also the rate of change:

From given function `m=0.28`
