Evaluate the expression shown below and write the answer as a fraction in simplert form.

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Use a transformation to solve the equation. w/4 = 8 can you also leave a detailed explanation on how this equation = 32
