Compute ∆y/∆x for the interval [2,6], where y = 4x − 7. What is the instantaneous rate of change of y with respect to x at x = 2?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

That’d be 9 years or something
