Question

Given the function f(x) = 2x +4 find the value of f(1/2).

A. 5
B. 4 ½
C. 6 ½
D. 6

Answer 1

Put \(x = \frac{1}{2}\) in the function..

Answer 2

\[\Large f(x) = 2x + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 2\left( \frac{1}{2} \right ) + 4 \]

Answer 3

I'll let you finish

Answer 4

After solving what you got @suckatmath17

Answer 5

i really have no clue what to do...

Answer 6

sorry

Answer 7

2 times one-half is ???

Answer 8

do i just times the bottom half of the fraction with 2?

Answer 9

So

\[\Large f(x) = 2x + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 2\left( \frac{1}{2} \right ) + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 1 + 4 \]

Answer 10

sry made a typo

Answer 11

im sorry i still dont get this at all!:(

Answer 12

\[ \Large 2 \times \frac{1}{2} \]

\[ \Large \frac{2}{1} \times \frac{1}{2} \]

\[ \Large \frac{2 \times 1}{1 \times 2} \]

\[ \Large \frac{2}{2} \]

\[ \Large 1\]


So \[ \Large 2 \times \frac{1}{2} = 1 \]

Answer 13

Hopefully you now see how 2 times one-half is 1?

Answer 14

yes i do thanks

Answer 15

So this means...

\[\Large f(x) = 2x + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 2\left( \frac{1}{2} \right ) + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 1 + 4 \]

\[\Large f\left( \frac{1}{2} \right ) = 5 \]

Answer 16

oh my gosh thanks soooo much
