F(x) = x + 7 and g(x) = x - 2, i honestly have no clue where to start im confused

A) {x | x ≠ 2}

Step-by-step explanation:

Domain is: all the values that x can be. Look for the following restrictions:

denominator (bottom) cannot be zero (set denomiantor ≠ zero)square root cannot be negative (set inside of square root ≥ 0)logs must be positive (set log > 0)

denominator is: x - 2 so set it unequal to zero and solve.

x - 2 ≠ 0

  +2   +2

x     ≠  2

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
