1. SWBAT to sketch and solve exponential functions WARM UP: Find the roots using your GDC! a)f(x) = x 2 +3x -2 b) f(x) = x 3 +3x – 3

2. Exponential Functions The independent variable is the exponent (or power in the equation Examples: f(x) = 2 x, g(x) = 7(3) x - 8 General Form: F(x) = ka x + c y = c is the horizontal asymptote y- int will be (0, k + c)

3. Asymptote A line that that a function approaches but never reaches. Graph f(x) = 4(2) -x + 2 Where is the asymptote? F(x) = 2

4. Bases vs Negative Exponents

5. F(x) = -4 -x + 1 What’s the asymptote? y = 1 What the y-int? (0,-3)
