evaluate this function:

Question

evaluate this function: 
w(t)=3t+2; Find w(2-t)

jim_thompson5910 · Answer

w(2-t) means "wherever you see a 't' replace it with '2-t' and simplify"

jim_thompson5910 · Answer

w(t)=3t+2

w(2-t)=3(2-t)+2

I'll let you simplify

Tell me what you get when you do

anonymous · Answer

okay good, i am just making sure my answer is correct. i got w(2-t)=8-3t

jim_thompson5910 · Answer

you got it, the answer is 

w(2-t) = 8-3t

or

w(2-t) = -3t+8

i have another one that i need help with. 

k(t)=$$\left| x+3 \right|$$ Find k(-4t)

jim_thompson5910 · Answer

hmm did you mean 

$$\Large k(t) = \left| t+3 \right|$$

Notice how it's t+3 and NOT x+3

anonymous · Answer

oh i am so sorry. that isn't even right. i accidently combined two problems when i glanced at my worksheet. it is supposed to be k(t)= t+4; Find k(-4t)

jim_thompson5910 · Answer

oh ok, that makes more sense

jim_thompson5910 · Answer

k(t)= t+4

k(-4t)= (-4t)+4

k(-4t)= -4t+4

jim_thompson5910 · Answer

That's all there is to it really
