Be careful how you handle this.

f(-7) = 3(-7)^2

f(-7) = 3* 49     Notice the minus sign disappears. That's because there are 2 of them.

How would you write 6 × 6 × 6 × 6 as an exponential expression?
stepan [7]
The answer is 6⁴.

Exponent is the number of times the factor is being multiplied. For example:
x * x = x²
x * x * x = x³
x * x * x * x = x⁴
....
So: 
6 * 6 * 6 *6 = 6⁴
