option B
Explanation:We need to check the otions for the movement of the line at the interval (negative infinity to positive one). The line should decrease at this point.
And at interval (positive one to positive infinity), the line should increase at this point.
From the options, In option B: on the y axis from negative infinity to positive 1, the line is decreasing. And on the y axis, from positive 1 to positive infinity, the is increasing.
Hence, the function is represented in option B
