Answer:

Step-by-step explanation:

f(3)=3(3)^2-7 so

f(3) = 3(9) - 7 and

f(3) = 27 - 7 so

f(3) = 20

Simplify the expression. Write the answer using scientific notation.
erik [133]
The answer is 5.88 x 10^22 because when you move your decimal point (which should be placed in between 5 and 8) to the right it turns 58800000000000 into 5.88. Then you count the numbers after the decimal which gives you 12.
( I’m pretty sure I made no sense, but hopefully it helped !! )
