Using only the values given in the table for the function f(x)=x^3+4x+3 what is the largest interval of x values where the function is increasing

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

sites:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
