Answer 2

(4, 3) maybe?

Answer 3

How did you get that? Because I'm wondering how to go about seeing where to look. Do I look at the x axis or y?

Answer 4

It seems like they just want the max output value (aka the y coordinate of that local max)

Answer 5

@MadR4t look for the highest point on the interval from x = -2 to x = 5. Erase the parts of the function not on the interval if it helps.

Answer 6

the local and global maximum/minimum confuses me so much because what is the point where it becomes global?

Answer 7

ok so i look at the x axis

Answer 8

local max = highest point in a certain region
absolute max or global max = highest point of the entire function

Answer 9

thank you! so it would be 4, 3?

Answer 10

they just want the max output, so 3 is the highest output (y coordinate) the function produces if you restrict the inputs from x = -2 to x = 5, and anything in between those x values.

Answer 11

thank you so much again

Answer 12

no problem
