Question

The functions f and g are defined as follows. ​

Answer 1

`\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}`

Here,

f(x)=-4x+2

we have to find the value of f(4)

• 
  `\sf{f(4)=-4(4)+2=-16+2=-14 }`

g(x)=
`{-3x^3-2 }`

we have to find the value of g(-2)

• 
  `\sf{g(-2)=-3(-2)^3-2 }`
• 
  `\sf{ g(-2)=-3(-8)-2 }`
• 
  `\sf{g(-2)=24-2=22 }`

More information:-

`\begin{gathered} \: \: \: \footnotesize{\boxed{\begin{array}c \\\\{\bf {f(4)}} & {\bf {-14}} \\ \\\\ \text{g(-2)} & \sf{22} \end {array}}}\end{gathered}`

Answer 2

f(4) = -14

g(-2) = 22

Explanation:

f(x) = -4x+2

Let x = 4

f(4) = -4*4 +2

= -16+2

= -14

g(x) = -3x^3 -2

Let x = -2

g(-2)= -3(-2)^3-2

= -3(-8)-2

= 24-2

=22
