- y=e^-xx is negative
- y=e^xx is positive
- y=-e^-x+0
- Asymptote y=0
- y=-e^x+0
- y=e^xy=e^0y=1Asymptote y=0
- Find y-intercept by letting x=0.
- y=e^(x)+1y=e^(0)+1y=2Asymptote y=1
- Ms Latha teaches 3 Loyalty a shortcut to remember exponential function graphs.
- y=lg/ln(-x)x is negative
- y=lg/lnxx is positive
- e is negative, therefore graph is flipped downwards. Do not forget the asymptote! It is always drawn as a dotted line.
- Asymptote x=0
- Equations to understand exponential function graphs.
- y=lgx0=lgx10^0=xx=1Asymptote x=0
- Find x-intercept by letting y=0.
- y=lg(x+1)0=lg(x+1)x+1=10^0x=0Asymptote x+1=0x=-1
- Ms Latha teaches 3 Loyalty a shortcut to remember Logarithm graphs.
- lg is negative therefore graph is flipped downwards. Do not forget the asymptote! It is always drawn as a dotted line.
- y=-lg(-x)
- y=-lgx
- Equations to understand logarithm graphs.
