Which situation can be represented by an exponential function? Select all that apply. Question 5 options: The value of a tractor depreciates 15% every year The cost of violin lessons at a twice-a-week rate The height of a tree doubles every two years The time it takes a firework to reach its maximum height

it is a reproduction.

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

50x5=$250
