Step-by-step explanation:
Given the expression
g(x) = x⁴ - 4x² + 7x - 8
we are expected to substitute x=2 into the expression and return the result
g(x) = (2)⁴ - 4(2)² + 7(2) - 8
g(x) = 16 - 4x4 + 14 - 8
g(x) = 16 - 16 + 14 - 8
g(x) =14 - 8
g(x) =6
From the substitution the roller coaster is travelling at speed of 6mph
