Look this function: f(x) = x2 - 4x - 21. Type the correct answer in each box to complete the statement. Write the points as ordered pairs, (a, b).​

Set square i think so

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
