Answer:
A
Step-by-step explanation:
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer: 6
Step-by-step explanation:
1. 3x - 6 = 12
2. add 6 to both sides
3. 3x = 18
4. x=6
I hope this is right
Answer:
f(x) = 2/5x^2.
Step-by-step explanation
Take the quadratic function x^2.
A vertical compression of 2/5 would transform it to:
f(x) = 2/5 x^2.
Replacing y by x in the first line we'll get x+8x-12=6, so 9x=18, x=2, y=1 being the only solution
