Document Summary
Examples of translations y = x y = x y = 1 x + = x. Example: y = 2x y = x2 x. The graph of an exponential function grows a lot faster as their power counterpart. ): (0, ax y = a x is ax reflected in the y-axis a x. Sketch: (1) sketch y = 2x y = 2( x+1) 3 y = 2( (x 1)) 3 (2) reflect over y-axis to get y = 2 x. January 21, 2019 (3) move 1 unit right to get y = 2 (x 1) (4) move 3 units down to get y = 2 (x 1) 3. Since they have the same base, you can equate the. Solution: ex+3 = 1 e2 ex+3 = e 2 x + 3 = 2 exponents. x = 2 3. January 21, 2019 (dr. allison) and solve for x x2 + 6 + 9 = 0 x.
