To solve for y, plus in -2 for x. The equation will look like:
y=(-2)^2+1

You must make sure to ALWAYS put negative numbers in parentheses when they are raised to a power.

Now, simply solve the problem:
(-2)^2=4
4+1=5

y=5 is the answer

Hope this helps!

b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639

Rainbow [258]

The exhibition of 7 birds will cost $2,450

<h3>How to calculate the total cost ?</h3>

The wildlife center charges a basic fee of $325 for a bird exhibition

When 5 birds were exhibited, $125 additional fee was charged

The additional fee for a bird is

= 125/5

= 25

Therefore the total cost of exhibiting 7 birds can be calculated as follows

= 325 + 25

= 350

350 × 7

= 2,450

Hence the total cost for the exhibition of 7 birds is $2,450
