help with these 6 questions
1. Find the zeros of the polynomial function.
f(x) = x3 + x2 – 42x
2. Solve and check the linear equation.
6[-6x + 6 + 4(x + 1)] = 6x + 2
3. Solve and check the linear equation.
0.40x – 0.20(50 + x) = -0.04(50)
4. Determine whether the given quadratic function has a minimum value or maximum value. Then find the coordinates of the minimum or maximum point.
f(x) = -x2 – 2x – 6
5. Convert to an exponential equation
log9 1â„81= -2
