The graphs of functions f(x) and g(x) = f(x) + k are shown: graph of line f of x going through ordered pairs 0, negative 2 and 2, 2. graph of line g of x going through ordered pairs 0, 2 and 1, 4. what is the value of k?
k = −2
k = 2
k = −4
k = 4

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

What is the value of 4x to the third +4x if x is 4
