It's an nth term for a sequence
So
I'm not really good at explaining but basically
3n means the three times table
And then to each number you add 12
So
3,6,9,12,15
(+12)
So your final answer is:
15,18,21,24

Which of the following are possible discriminants for a quadratic function that crosses the x-axis twice? Check all that apply.

Sedaia [141]

Answer:

1001

Step-by-step explanation:

If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in $ax^2+bx+c$ with discriminant $b^2-4ac$ , the following is true:

If $b^2-4ac>0$ , then the quadratic has two real solutions
If $b^2-4ac=0$ , then the quadratic has one real solution
If $b^2-4ac$ , then the quadratic has no real solutions

Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.

Find: f(g(2))<br> f(x)=x^2 -3x-2<br> g(x)=5x-7

REY [17]

Answer:

-2

Step-by-step explanation:

g(2) = 5*2-7 = 3

f(g(2)) = f(3) = 3^2 - 3*3 - 2

= 9-9-2

= -2
