When using the quadratic formula to solve a quadratic equation (ax2 + bx + c = 0), the discriminant is b2 - 4ac. This discriminant can be positive, zero, or negative. Create three unique equations where the discriminant is positive, zero, or negative. For each case, explain what this value means to the graph of y = ax2 + bx +
Many students incorrectly evaluate the indeterminate forms of type 0^0 , type ∞^0 , and type 1^∞ as 1 because they think that "anything to the zero power is 1" and "1 to any power is 1." These rules are indeed true for powers of numbers. But 00 , ∞0 , and 1∞ are not powers of numbers but descriptions of l
