What is the value of x in the equation 2(x-4) = 4(2x + 1)?

Write the expression as a single natural logarithm. 2 in a - 4 in y

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
