ANSWER
The maximum value is 625
EXPLANATION
The height of the stick that the bird dropped is modeled by the function;
This function is already in the vertex form.
Let me rewrite it clearly for you to see.
When we compare this to;
we have h=0 and k=625.
k=625 is the y-value of the vertex.
This is the maximum value on the graph of this function.
Answer:
<em>x² - 28x√x + 294x - 1372√x + 2404 </em>
Step-by-step explanation:
f(x) = + 3
g(x) = x - 7
h(x) = √x
f(g(h(x))) - ?
g(h(x)) = √x - 7
f(g(h(x))) = + 3 = ( √x - 7 )² × ( √x - 7 )² + 3 =
= (x - 14√x + 49)(x - 14√x + 49) + 3 =
= x² - 14x√x + 49x - 14x√x + 196x - 686√x + 49x - 686√x + 2401 + 3 =
= <em>x² - 28x√x + 294x - 1372√x + 2404</em>
