Question

1 the score for a video game is calculated using f(x) = 4.5x² + 7x + 2, where x represents the levels completed. if alex completes 50 levels, what will his score be?
a 4,902
b 577
c 2,852
d 11,602
2 a part of function g is graphed on a coordinate plane.

Explanation:

Step1: Substitute $x=50$ into formula

$f(50)=4.5(50)^2 + 7(50) + 2$

Step2: Calculate squared term

$4.5(50)^2 = 4.5\times2500 = 11250$

Step3: Calculate linear term

$7(50) = 350$

Step4: Sum all terms

$11250 + 350 + 2$

Answer:

D. 11,602
