Adiver went 25.65 feet below the surface of the ocean and then 16.5 feet further down he then rose 12.45 feet write and solve an expression to find the

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
