If (-2) = -14 for f(x) = 3x -b; find b? -
Verizon [17]

Answer:

<em>The value of b is</em><em> 8</em><em>.</em>

Step-by-step explanation:

The given function is,

f(x) = 3x -b

The given data is,

f(-2)=-14

i.e when the value of x is -2, then the value of the function is -14.

Putting all the values,

\Rightarrow -14 = 3(-2) -b

\Rightarrow -14 = -6 -b

\Rightarrow b=-6+14

\Rightarrow b=8

Therefore, the value of b is 8.
