Consider the function f(x) = x+7x - 8. a) Find when f(x) = - 20 f(x) = -20 when x = Writing any values as simplified fractions if necessary. If there are multiple values, separate them with a comma. If there are no values, input "DNE". b) Use the information from part a) to find two points that lie on the graph of f(x). The two points are Write ordered pairs, writing any values as simplified fractions if necessary. If there are multiple points, separate them with a comma. If there are no points, input "DNE".
