Question

F(x) =x + 3/2
For the function f defined above, what is the value of f(-1)

Answer 1

0.5

Explanation:

Plug in -1 as x into the function:

f(-1) = -1 + 3/2

f(-1) = 0.5

Answer 2

`\bf \underline{ \underline{Given : }}`

f(x) =x + 3/2

`\bf \underline{ \underline{To \: be \: calculated : }}`

what is the value of f(-1) ?

`\bf \underline{ \underline{Solution : }}`

`\sf{f(x) = x + (3)/(2) }`

`\rightarrow \sf {f( - 1) = ( - 1) + (3)/(2) }`

`\rightarrow \sf{f( - 1) = ( - 2 + 3)/(2) }`

`\rightarrow \sf{f( - 1) = ( 1)/(2) }`

`\rightarrow \sf {f( - 1) = 0.5}`
