Question $10$

$(1$ point$)$

Find the minimum or maximum value of the function. Describe the domain and range of the function, and where the function is increasing and decreasing.

$h(x)=3x^2-6x-2$

a The minimum value is $-5.$ The domain is all real numbers and the range is $y-5.$ The function is decreasing to the left of $x=1$ and increasing to the right of $x=1.$

b The maximum value is $7.$ The domain is all real numbers and the range is $y7.$ The function is increasing to the left of $x=-1$ and decreasing to the right of $x=-1.$

c The maximum value is $-5.$ The domain is all real numbers and the range is $y-5.$ The function is increasing to the left of $x=1$ and decreasing to the right of $x=1.$

d The minimum value is $7.$ The domain is all real numbers and the range is $y7.$ The function is decreasing to the left of $x=-1$ and increasing to the right of $x=-1.$
