Question

If h(x+2)=1/2 x , then h(-2) is

Answer 1

just plug x=-4 to both sides
what u get

Answer 2

how you get -4

Answer 3

how would i show my work for this problem

Answer 4

h(x+2), if we plug x=-4 it would be h(-2), right ?

Answer 5

yes than wat would i do next

Answer 6

apply x=-4 to right side also, what u get ?

Answer 7

-2 could you show me how to write it out solving it

Answer 8

h(x+2)=1/2 x
plug x= -4,
h(-4+2) = 1/2 * (-4)
h(-2) = -2
u are right

Answer 9

is -2 the answer than

Answer 10

sure...

Answer 11

is that right or do i have to do another step

Answer 12

well, we have another way to solve it....
h(x+2)=1/2 x
let u=x+2, it means x=u-2
therefore, we get :
h(u) = 1/2 * (u-2)
now, if u we change again to x, gives
h(x) = 1/2 * (x-2)
now, plug x=-2
h(-2) = 1/2 * (-2-2)
h(-2) = 1/2 * -4 = -2

Answer 13

is -2 still the answer thou

Answer 14

yes

Answer 15

ok thanks can yu help with another problem as well

Answer 16

sure..

Answer 17

ok
