the graph of h is the graph of f(x)=x^2 translated 4 units left and 7 units down. Write the function H in vertex form.
adoni [48]

Answer:

f(x)=a(x - h)2 + k

Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.

The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):

x - h = 0

-2 - h = 0

-h = 2

h = -2

So the function ends up looking like:

f(x)=a(x - (-2))2 + 2

Subtracting a negative cancels the signs out to make a positive:

f(x)=a(x + 2)2 + 2

Is my answer correct?
ziro4ka [17]
Here is the answer to the given problem above. 
Here is the exponential function to model this situation:
<span>f(x) = 420(0.79)x
Now, solve with the given values.
</span><span>P(t)=420×(.79<span>)^t</span></span> <span><span>P(5)=420×(.79<span>)^5</span>=129
So the answer would be 129 animals.
Hope this answer helps. Thanks for posting your question!</span></span>
