A factory is 5 kilometers downstream on the other side of the river. It costs Php 100.00 per meter to run the power lines on the land and Php 150.00 per meter to run them underwater. Write the cost C of running the line from the power station to the factory as a function of x. Figure: Power Station -km 5-X Factory 2. Given f(x) = x2 - 2x + 1, find f(2 + b) - f(2) b 3. Given: f (x) = x2 - 2x + 4, g(x) = = and h(x) = VX -1 find fthig(x)1}
