question 144

Multiple Choice

The number of people present at a stadium holding a big rock concert can be estimated with the following function: $y = 13252 x ^ { 0.74 } + 0.54 x + 102$ where y is the number of people present and x is the amount of time since 3:00 p.m. on the day of the concert. Rewrite the model with x equal to the amount of time since 1.00 p.m.

• A) \(y = 13,252 ( x - 2 ) ^ { 0.74 } + 0.54 x + 102\)
• B) \(y = 13,252 ( x - 2 ) ^ { 0.74 } + 0.54 ( x - 2 ) + 102\)
• C) \(y = 13,252 ( x + 2 ) ^ { 0.74 } + 0.54 ( x + 2 ) + 102\)
• D) \(y = 13,252 ( x + 2 ) ^ { 0.74 } + 0.54 x + 102\)
