|---|---|
| What type of graph is this? Decay or Growth: f(x)=1/2 x 3^x | Growth. Because the base number is bigger than one. |
| What type of graph is this? Decay or Growth: f(x)=1/4^x+1 + 3 | Decay. Because the base number is less than one. |
| What is ALWAYS the same in exponential functions? | The domain. ALWAYS: (- infinity, + infinity) |
| How do you figure out the range of an exponential function? | If the graph is exponential growth it goes: (k, infinity). If the graph is decay, it goes: (infinity, k) |
| What is the standard exponential equation/formula? | y= a x b ^ x-h + k |
| How do you figure out the Horizonal asymptote in exponential functions? | It is the K value |
| What will the end behaviors always be? | Also, the K value |
| To find the y-int only give the equation, what do you do? | You set the x-values in the equation equal to zero and solve for y. |
| How do you figure out the base number (which helps determine if the graph is growth or decay)? | It is the value with an x as an exponent. |
| The value "e" is approximately equal to what? | ~2.718 |
| what is "e^0" | 1 |
| what is "e^1" | 2.718 |
| what is "e^2" | 7.389 |
| When graphing the parent function of e, what values should you use for x to find y? | 0, 1 , 2 |
| When graphing functions besides "e" parent function, what numbers should you use? | -1,0,1 |
| How do you turn a percent into a decimal? | Divide the percent by 100 |
