The function g is defined as follows for the domain given. g(x) = 2 - 2x , domain = \{- 1, 0, 1, 2\} Write the range of g using
Musya8 [376]

Explanation:

The function is given below as

g(x)=2-2x

The set of domains is given below as

\lbrace-1,0,1,2\rbrace

Step 1:

Put x=-1

\begin{gathered} g(x)=2-2x \\ g(-1)=2-2(-1) \\ g(-1)=2+2 \\ g(-1)=4 \end{gathered}

Step 2:

Put x=0

\begin{gathered} g(x)=2-2x \\ g(0)=2-2(0) \\ g(0)=2 \end{gathered}

Step 3:

Put x=1

\begin{gathered} g(x)=2-2x \\ g(1)=2-2(1) \\ g(1)=2-2 \\ g(1)=0 \end{gathered}

Step 4:

Put x=2

\begin{gathered} g(x)=2-2x \\ g(2)=2-2(2) \\ g(2)=2-4 \\ g(2)=-2 \end{gathered}

Hence,

The range of g(x) using set notation will be

\Rightarrow\lbrace4,2,0,-2\rbrace

Hence,

The graph of g(x) is given below as

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

f(x)=3x^2+2x-5

To evaluate the value of f(-2), substitute -2 for x. Thus:

f(-2)=3(-2)^2+2(-2)-5

Square first:

f(-2)=3(4)+2(-2)-5

Multiply:

f(-2)=12-4-5

Now, subtract:

f(-2)=8-5=3

So:

f(-2)=3

And we're done!
