Question

I need help understanding what the question means

k:m ---> 7+msquared when k(-4)

Answer 1

msquared I assume you mean \( m^2\) which you can write as m^2
k:m ---> 7 + m^2

it looks like they are defining a function k(m)= 7+m^2
and want you to evaluate it when m= -2
in other words, replace m with (-2) and simplify: 7+ (-2)^2

Answer 2

ok but uh where did -2 come from exactly?

Answer 3

oops! I mean do 7+(-4)^2

when k(-4)

typically, you define a function with a name (k in this case) and then (variable) where variable is m in this problem)
k(m) = some rule that uses m
in this case
k(m)= 7+m^2

and then
k(-4) means "replace m with -4 in 7+m^2"

Answer 4

oh ok lol thanks :D my mom is a math wiz and we are doing my math work but this is something she wasn't to sure of so we had to make sure anyway thanks again :)

Answer 5

I'm guessing that is what they mean. A screen shot or photo of the book might help (assuming they explain it)
