Question

Graphing an exponential function. Am I right in performing these steps to graph this function?

f(x) = 3(2)^2(x-4) + 5

1. Select a value for x. x=-2
2. Subtract 4 from -2. -2 -(-4) = 2
3. Multiply 2 and 2. 2*2 = 4
4. Raise 2 to the power of 4. 2^4 = 16
5. Multiply 16 by 3. 16*3 = 48
6. Add 5 to 48. 48 + 5 = 53

(-2, 53)
