Consider the function a defined by the rule a(x) = integral_1^x f(t) dt where f(f) = 4 - 2t compute a(1) and a(2) exactly use the first fundamental theorem of calculus to find an equivalent formula for a(x) that does not involve integrals that is, use the first ftc to evaluate integral_1^x (4 - 2t) dt. a(x) = observe that f is a linear function what kind of function is .4? answer ? using the formula you found above for a(x), that does not involve integrals, to compute a(x). while we have defined f by the rule f(t) = 4 - 2t it is equivalent to say that f is given by the rule f(x) = 4 - 2x. what do you observe about the relationship between a and f?
