T\The answer would be 3 6/10, or 3.6.
Since 5x is equal to y.we can write 5x instead of y in the equation.and then solve the equation
Equation: f(x)=(1/5)x^2 or f(x)=(0.2)x^2
Check:
f(0)=(1/5)(0)^2
f(0)=(1/5)(0)
f(0)=0✓
f(5)=(1/5)(5)^2
f(5)=(1/5)(25)
f(5)=5✓
Answer:
Solve 3-6x >= 0
6x <= 3
x <= 1/2
Domain: All Real Numbers <= 1/2
15x^2+21x+6 that’s the answer
