Answer:
A) rational number
Step-by-step explanation:
56 is a rational number because it can be expressed as the quotient of two integers like 56 ÷ 1.
f(x) = (x - 4)^2 - 5
Vertex (4 , -5)
This function opens upward and has min. value = -5
So range y >= - 5
So answer is A. -5 <= f(x) < ∞
Answer:
The slope of the line is -5
I think that the baby would weight 18 pounds if her weight doubles in six months
Answer:
3
Step-by-step explanation:
So we have the function:

To evaluate the value of f(-2), substitute -2 for x. Thus:

Square first:

Multiply:

Now, subtract:

So:

And we're done!
