Let f(t) =22 −44 and consider the two area functions a(x)=∫2xf(t) dt from 2 to x and f(x)=∫5xf(t) dt. from 5 to x. evaluate a(33) and a(44). then use geometry to find an expression for a(x) for all x ≥22.

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
