To three decimal places, find the value of the first positive x-intercept for the function f(x) = 2cos(x + 3). 2.712 −1.429 1.712 −1.712

The first positive x-intercept for the function is .

Step-by-step explanation:

The x-intercept is the point where a line crosses the x-axis,

To find the x-intercept for the function , let's substitute f(x) = 0 into the equation and solve for x:

We want the value of the first positive x-intercept so we take the value of when n = 0.

We can check our answer with the graph of the function. We can see that we get the same answer.
