Question

Evaluate the function. Round your answer to four decimal places, if necessary. $$ f(x)=2.4(4)^{-x+1}+2.2 $$, for $$ f(-2) $$ $$ f(-2)= $$

UpStudy AI · Accepted Answer

Substitute $$ x=-2 $$ into the expression $$ 2.4(4)^{-x+1}+2.2 $$.
Evaluate the expression by following steps:
- step0: Evaluate:
  $$2.4	imes 4^{-x+1}+2.2$$
- step1: Substitute:
  $$2.4	imes 4^{-\left(-2ight)+1}+2.2$$
- step2: Add the numbers:
  $$2.4	imes 4^{3}+2.2$$
- step3: Multiply the numbers:
  $$153.6+2.2$$
- step4: Add the numbers:
  $$155.8$$
The value of $$ f(-2) $$ is $$ 155.8 $$ when rounded to four decimal places.
$$ f(-2) = 155.8 $$
