IN NEED OF HELP THX

Question

You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes to get to school, measured in minutes, is modeled using the function g(x) = x⁴ − 3x² + 4x − 5, where x is the number of stops the bus makes. If the bus makes 2 stops after you board, how long does it take you to get to school?

 A.1 minute 

B.3 minutes 

C.7 minutes 

D.11 minutes

Answer 1

C. 7 minutes

Substitute 2 in for x in the function

g(x) = x⁴ − 3x² + 4x − 5

g(x) = 2⁴ - 3(2²) + 4(2) - 5

g(x) = 16 - 12 + 8 - 5

g(x) = 24 - 17

g(x) = 7

I hope you find this useful. If you have any questions please send me a message.

Answer 2

"using the function g(x) = x⁴ − 3x² + 4x − 5", find g(2). So, give x the value of 2.

g(2) = (2)⁴ - 3(2)² + 4(2) - 5

g(2) = 16 - 12 + 8 - 5

g(2) = 7

The time it takes you to get to school is 7 minutes.
