Please help
The following graph describes function 1, and the equation below it describes function 2:
Function 1
graph of function f of x equals negative x squared plus 8 multiplied by x minus 15
Function 2
f(x) = −x2 + 2x − 15
Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)

Best ResponseYou've already chosen the best response.1\[Funtion 1: x ^{2}+8x120\] \[Function 2: x ^{2}+2x15\] Looking at maximum values ....we could differentiate it and equal it to zero? or we could factorise it. may i know thw topic please?

Best ResponseYou've already chosen the best response.1in that case we can factorise it and see which function has the larger maximum (Or draw the functions)

Best ResponseYou've already chosen the best response.1or look at y intercepts.. the first function crosses y axis at 120 where as the second function crosses at y axis 15 .. so the first one is more 'below' than the second.

Best ResponseYou've already chosen the best response.1from the question what i can sort of gather is that we are looking at the values right.. at which point is their maximum ? if your allowed to use a graphics calculator you can see the following information:

Best ResponseYou've already chosen the best response.1so i guess we can look at the corresponding yvalues and see that Function 2 has a higher y value ? I hope i am doing this correct.. is there any way to check it?

Best ResponseYou've already chosen the best response.1and if we sketch both in same graph , function will sit above function 1, meaning function 2 has a larger maximum
