Answer: a) k >4.08
b) k = 4.08
c) k<4.08
Step-by-step explanation:
Since we have given that

a) For what values of k will the function have no zeros?
It mean it has no real zeroes i.e. Discriminant < 0
As we know that

Here, a =-3
b = 7
c = -k
So, it becomes,

b) For what values of k will the function have one zero?
It means it has one real root i.e equal roots.
So, in this case, D = 0
So, it becomes,

c) For what values of k will the function have two zeros?
It means it has two real roots.
In this case, D>0
So, it becomes,

Hence, a) k >4.08
b) k = 4.08
c) k<4.08
Answer: {-16,4,92}. 2) {-16,10 ,42}. 3) {0,10,42}. 4) {0,4,92}. 5 The function f(x) = 2x. 2 + 6x - 12 has a domain.
Step-by-step explanation:
Just trying to win the CONTEST BUT GOOOOD LUCK
7 because 7 x 7 is 49 but if you add 7 and 7 it gets to 14 7 is the answer
so if you do a different number you will be wrong
