Question

Integrals with variables.

Answer 1

Answer:

a = 5, b = 14

Step-by-step explanation:

∫₁¹⁴ f(x) dx is the area under f(x) between x = 1 and x = 14.

∫₁⁵ f(x) dx is the area under f(x) between x = 1 and x = 5.

Therefore, the difference is the area under f(x) between x = 5 and x = 14.

∫₁¹⁴ f(x) dx − ∫₁⁵ f(x) dx = ∫₅¹⁴ f(x) dx
