Ben had a Test today on absolute value functions. I asked him if he wanted to review first. He shrugged his shoulders and said let’s get it over with.. Ben worked through the problems. I asked him to”explain in words” the transformations. He asked me what I meant by that and I said “up 3, down 2, reflect over the y/axis, shrink by a 1/2, etc”. On his test he wrote D4 and L1. I told him I understood what he meant but another teacher or professor might require proper description. .I will grade the test and we will review it Monday.
