A) The x-intercept decreases.
Step-by-step explanation:
Hi, for the function f(x) = mx + b, if the value of b decreases, but the value of m remains the same, The x-intercept decreases.
For example
For b=2, m =1 and x =0 (since the y-value of a linear equation when it crosses the x-axis is 0 )
f(x) =0(1)+2 =2 (x-intercept)
For b= 1 (b decrease) ,m =1 and x =0
F(x) = 0(1) +1 = 1 (x_intercept also decreases)
So, the correct option is A) The x-intercept decreases.

The cosine is a trigonometric function. The cosine of an angle is done by dividing the length of a side of a traingle adjacent to the acute angle by the length of the longest side or the hypotenuse. For a complete list of angles and measurements, see the figure attached.
