The values of the functions are:
1. y = f(-7) = 128
2. y = f(5) = 0.0313
<h3>How to Find the Value of a Function?</h3>
We can evaluate a function by substituting the given value into the equation of the function, then simplify.
Given the function, y = f(x) = (1/2) ^ x
1. Find the value of f(-7):
y = f(-7) = (1/2)^-7
y = f(-7) = 2^7
y = f(-7) = 128
2. 1. Find the value of f(5):
y = f(5) = (1/2)^5
y = f(5) = 0.0313

Answer:
diameter of a circle
Step-by-step explanation:
1. x² - 6x + 8
4*2 equals 8 and if you add 4 and 2 it gives you 6
-4-2= -6
=(x-4)(x-2)
3. the answer is A
if you plug in the points into the equation y=x
y= 1/2x + 4
given point: (4,6) x=4 y=6
6= 1/2(4)+4
6=6
1.06(12.25 + x) = 19.08
12.25 + x = 19.08/1.06 = 18
x = 18 - 12.25 = 5.75
Therefore, the cost of the cat food is $5.75
