F(x)= (x+4) ^{2} -13 is the answer
<span />
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
Answer:

Step-by-step explanation:
The y intercept form for the equation of a line is

You should note that <em>c</em> represents the y-intercept of the line (where the line touches the y-axis)

Thus should be fun I know I might do
Answer:
The test hypothesis is
:

Step-by-step explanation:
Consider the provided information.
Null hypothesis refer the population parameter is equal to the claimed value.
If there is no statistical significance in the test then it is know as the null which is denoted by
, otherwise it is known as alternative hypothesis which denoted by
.
The historical average lifetime for cartridges produced by the current process is 1502.5 pages.
Hence, the test hypothesis is
:
