Equation of a exponential function
WebWe can find the formula of an exponential function by using two points on the curve, substituting them into the formula y = abx, and solving the system of two equations in two unknowns. Given a graph or a table of values, … WebAug 4, 2024 · 1 Answer. Sorted by: 4. First thing about exponential function is, its values/graph approximates zero, so the whole graph is lifted by two (that's the + 2 there). Once we subtract the 2, we see that the …
