How do you remember the way to use the x^2 term of a quadratic function to tell whether the function has a maximum or a minimum value

Which function families have maximums and minimums? 1.)linear absolute value functions and exponential functions 2.) linear absolute value functions and quadratic functions 3.) linear absolute value functions and linear functions 4.) linear absolute value functions and constant functions

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

What is the 9th term in the geometric sequence described by this explicit formula? an=-6. (2)(n-1) apex
