These are the terms of a geometric sequence with a common ratio r
r = =
=
= -
the next 2 terms are obtained by multiplying the previous term by r
16 × - = - 8
- 8 × - = 4
Answer:
Step-by-step explanation:
the quadratic function should be as follows:
Now let's confirm that the zeros of the function are 0 and 8
Therefore we can see that if x = 0
the equation is fulfilled
And we also have
for this expresion to be equal to zero:
thus, if x = 8
the equation is also fulfilled
The zeros of the quadratic function are 0 and 8.
