At which values of x does the graph of f(x) = cos x intersect the x-axis? 0 π/2π3π/22π

At the graph of f(x) = cos x intersect the x-axis.

Step-by-step explanation:

Given the function f(x)=cosx

We have to choose the value of x for which the graph intersect the x-axis.

The graph intersect the x-axis when at any point of x value of y i.e f(x) is 0.

Hence,

At two values of x i.e at π/2 and 3π/2 the value of y is 0.

Hence, at

1.0

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
