Answer:
Option D, Yes, Devon should have evaluated f(3)
Step-by-step explanation:
f(x) = x^3 + x^2 − 10x + 8
<u>Step 1: Evaluate using F(3) NOT f(-3)</u>
f(3) = 3^3 + 3^2 - 10(3) + 8
f(3) = 27 + 9 - 30 + 8
f(3) = 14
Since the factor is (x - 3) the x value is x - 3 + 3 = 0 + 3 -> x = 3 not x = -3
Answer: Option D, Yes, Devon should have evaluated f(3)
1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?
[ Triple the quantity of a number “n” ] 3n
[ plus 4 ] + 4
[ equals 27 ] = 27
[ all together ] <u>3n + 4 = 27</u>
<u />
<u>Solving:</u>
[ given ] 3n + 4 = 27
[ subtract 4 from both sides ] 3n = 23
[ divide both sides by 3 ] n = 7 
2:Seventeen equals seven less than three times a number “n” what would the expression look like?
[ Seventeen equals ] 17 =
[ seven less than ] - 7
[ three times a number “n” ] 3n
[ all together ] <u>17 = 3n - 7</u>
<u />
<u>Solving:</u>
[ given ] 17 = 3n - 7
[ add 7 to both sides ] 24 = 3n
[ divide both sides by 3 ] 8 = n
Have a nice day!
