How would you solve this without a graphing calculator? -
Two functions are shown below.

f(x)=3x^2+14x-5

g(x)=11x+13

At which points do the graphs of the two functions intersect?

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
