What is a logical first step in solving the equation? (a) (x+ 4)2 = 81 Simplify the exponential part. Subtract 81 from both sides. Take the positive and negative square roots of both sides. Square both sides. Subtract 4 from both sides. (b) (x + 4)2 + 4= 81 Subtract 4 from both sides. Take the positive and negative square roots of both sides. Subtract 81 from both sides. Subtract 8 from both sides. Square both sides. (c) +x-7 Square both sides. Multiply both sides by x. Factor out x. Subtract 7 from both sides. Take the positive and negative square roots of both sides.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
