Given f (x) = -3 + 5, solve for x when f (x) = -4
2 answers:
Answer:
x = 3
Step-by-step explanation:
Hello!
Think of this as a linear equation: y = -3x + 4.
If f(x) = -4, it means that y = -4.
Plug in the value for y and solve for x.
<h3>Solve</h3>
- f(x) = -3x + 5
- y = -3x + 5
- -4 = -3x + 5
- -9 = -3x
- 3 = x
The value of x is 3.
The value of x when f(x) = -4 is 3
<h3>How to solve the function?</h3>
The function is given as:
f(x) = -3x + 5
When f(x) = -4, we have:
-4 = -3x + 5
Subtract 5 from both sides
-3x = -9
Divide both sides by -3
x = 3
Hence, the value of x when f(x) = -4 is 3
