Answer:
g(x) =
Step-by-step explanation:
Parent function given in the graph attached is,
f(x) =
Function 'f' passes through a point (1, 1).
If the parent function is stretched vertically by 'k' unit,
Transformed function will be,
g(x) = k.f(x)
Therefore, the image of the parent function will be,
g(x) =
Since, the given function passes through (1, 2)
g(1) = = 2
⇒ k = 2
Therefore, image of the function 'f' will be,
g(x) =
Well, notice, we can pretty much see the x-intercepts if we set f(x) = 0, clearly they're just 6 and -2,
now, this is a quadratic equation, since it only has 2 solutions at most, recall your fundamental theorem of algebra.
so, the vertex will be right in middle of those two x-intercepts.
what's between -2 and 6?, well is +2 or just 2, so
x = 2.
so we know the x-coordinate for the vertex is the halfway point of 2, what's the y-coordinate?
f(x) = y = (
2 - 6)(
2 + 2)
y = ( - 4)( 4 )
y = -16thus the vertex is at, well you already know.
The given expression is,
y = f(x)
This mean that the value of the function is the value that correponds to the y value for a particular x.
From the graph we can see that,
Thus, f(0) = 2.
Answer:
20.50
Step-by-step explanation:
<u>9/4</u> as a decimal is <u>2.25</u>. an you need to find the ice cream Cassie used the way Would say is multiply <u>2.25</u> by 9 and you get <u>20.5</u>. I hope this helps
