Step-by-step explanation:
If you would like to know the value of b^2 - 4 * a * c, you can calculate this using the following steps:
x * (x + 8) = 9
x^2 + 8x - 9 = 0
ax^2 + bx + c = 0
a = 1
b = 8
c = - 9
D = <span>b^2 - 4 * a * c = 8^2 - 4 * 1 * (-9) = 64 + 4 * 9 = 64 + 36 = 100
The correct result would be 100.</span>
Answer: 20
Step-by-step explanation: because 3+17=20
A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
