Question

Evaluate the function f(x)=2x + 2, when x=1

Answer 1

f(x) = y = 2x+2, and we need to know what y is when x =1. So, everywhere you see x, just plug 1 in it's place. y = 2(1) + 2. What is 2(1) + 2?

Answer 2

4

Answer 3

yup. so, f(x) = 2x + 2 at x = 1 is 4. So, f(x) = y = 4

Answer 4

Thanks, Can you help with one other one? Equations are hard for me lol

Answer 5

Yeah def. Ask away

Answer 6

Evaluate the function g(t)=5/2t - 3/2, when t = 3

Answer 7

Just as jtug6 has said, wherever you see t, just put in 3
You will have\[\frac{ 5 }{ 2\times3 }-\frac{ 3 }{ 2 }\]

Answer 8

Yup! Exactly. Sorry for late response was helping someone else

Answer 9

2 x 3 is 6 So then we can proceed by finding the L.C.M of the two denominators

Answer 10

so, 2?

Answer 11

6 is one of my possible answers

Answer 12

The L.C.M. of 6 and 2 is what?

Answer 13

Oh, Duh, 6

Answer 14

So we will then have\[\frac{ 5-9 }{ 6 }\]which is\[\frac{-4}{6}\] which is equivalent to\[-\frac{2}{3}\]

Answer 15

Thanks!
