Answer:
The answer to your question is 1.- f(x) = 2x + 5 2.- f(x) = 11x - 10
3.- f(x) = -3x + 5 3.- f(x) = x² + 7
Step-by-step explanation:
Equations
1.- y - 2x = 5
- Solve for y
y = 2x + 5
- Use function notation
f(x) = 2x + 5
2.- y - 3x = 8x - 10
-Solve for y
y = 8x - 10 + 3x
- Simplify
y = 11x - 10
-Convert to function notation
f(x) = 11x - 10
3.- 2y + 6x = 10
-Solve for y
2y = -6x + 10
y = -6/2x + 10/2
-Simplify
y = -3x + 5
-Convert to function notation
f(x) = -3x + 5
4.- - x² = 7 - y
-Solve for y
y = x² + 7
-Convert to function notation
f(x) = x² + 7
