Answer:
ans x=4
Step-by-step explanation:
- 5x + 7 = -13
- 5x = -13 -7
- 5x= -20
- x = -20/5
- x = -4
- so the answer is x= -4
$14.36 is the change.
$5.64 cost. 1.88*3=5.64
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
