You’ve learned about function notation in previous lessons, but could you use function notation to add two functions? how do you think you could simplify f(x) + g(x) if f(x) = 3x + 2 and g(x) = 4x? what about a function of a function such as f(g( how do you think f(g(x)) could be simplified? what situations can you think of where combining functions would be useful?

20 points for the answer. this is for real , don't put random ! a rectangle has a length of 4 centimeters and a width of 7 centimeters. what is the effect on the perimeter when the dimensions are multiplied by 5? the perimeter is increased by a factor of 5. the perimeter is increased by a factor of 20. the perimeter is increased by a factor of 25. the perimeter is increased by a factor of 100.
