Need help finding any relative extrema (don't know if I'm correct) and identifying any intervals over which the function is increasing or decreasing (in interval notation) thanks

Find any relative extrema of the function. List each extremum along with the x-value at which it occurs. Identify intervals over which the function is increasing and over which it is decreasing. Then sketch a graph of the function. G(X) = -x +x2+x+7 Identify any intervals over which the function is increasing or decreasing. Select the correct choice below and fill in the answer box(es) within your choice. O A. The function G(x) is decreasing over the interval(s) and is not increasing anywhere. (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) O B. The function G(x) is increasing over the interval(s) 3 and decreasing over the interval(s) co , - 3 , (1,00 ) (Type your answers in interval notation. Use integers or fractions for any numbers in the expressions. Use a comma to separate answers as needed.) C. The function G(x) is increasing over the interval(s) and is not decreasing anywhere. (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.)
