Evaluating Functions and Expressions

The video tutorial explains how to determine the output of a function when H equals 2. It starts by introducing the function B(H) = 50 * 2^H - 18H and then substitutes H with 2. The tutorial walks through the calculation steps, showing how to compute 50 * 2^2 and subtract 18 * 2, resulting in a final output of 164. The video concludes by summarizing the process and confirming the result.

What is the initial expression given for B of H?

• B of H equals 50 plus 2 to the h minus 18 h

• B of H equals 50 minus 2 to the h plus 18 h
