Finding an Exponential Equation with Two Points and an Asymptote
Finding an Exponential Equation with Two Points and an Asymptote Find an exponential function whose asymptote is y=0 and passes through the points (2,16) and (6,256). Substitute into either equation to find a Substitute into y=abx twice Larger exponent first ÷ Subtract Exponents Divide #s Find the Root
Finding an Exponential Equation with Two Points and an Asymptote Find an exponential function that passes through (-3,239) and (2,-3) and has a horizontal asymptote of y = -4. Asymptote c=-4 Substitute into twice: Larger exponent first + 4 + 4 Substitute into either equation to find a + 4 + 4 Rewrite into y=abx Divide #s ÷ Subtract Exponents Find the Root
Finding an Exponential Equation with Two Points and an Asymptote Find an exponential function that passes through (3,12.5) and (4,11.25) and has a horizontal asymptote of y = 10. Asymptote c=10 Substitute into twice: Substitute into either equation to find a Larger exponent first – 10 – 10 – 10 – 10 Rewrite into y=abx Divide #s ÷ Subtract Exponents Warning: This is not addressed a lot in the homework but will be assessed.
