To match: the given graph with its function and verify with graphing window [−4.7,4.7]×[−3.1×3.1] .
The given graph matches with option (k) y=int(x+1) .
Given information: The given graph is,
Formula used:
The graph of the function y=f(x+h) is found by shifting the graph of the function y=f(x) by h units left.
Calculation:
See the shape of the graph.
The graph resembles to the graph of y=intx .
Consider the basic function y=intx .
Shift the graph 1 unit to left such that the x -intercept is 1 .
Thus, the graph of the function is y=int(x+1)
The given graph matches with option (k).
Graph the function in the graphing window [−4.7,4.7]×[−3.1×3.1], by using graphing calculator:
Hence, the graph matches with option (k) y=int(x+1) .

(Type an integer or decimal.)arrow_forwardRama/Shutterstock.com Romaset/Shutterstock.com The power station has three different hydroelectric turbines, each with a known (and unique) power function that gives the amount of electric power generated as a function of the water flow arriving at the turbine. The incoming water can be apportioned in different volumes to each turbine, so the goal of this project is to determine how to distribute water among the turbines to give the maximum total energy production for any rate of flow. Using experimental evidence and Bernoulli's equation, the following quadratic models were determined for the power output of each turbine, along with the allowable flows of operation: 6 KW₁ = (-18.89 +0.1277Q1-4.08.10 Q) (170 - 1.6 · 10¯*Q) KW2 = (-24.51 +0.1358Q2-4.69-10 Q¹²) (170 — 1.6 · 10¯*Q) KW3 = (-27.02 +0.1380Q3 -3.84-10-5Q) (170 - 1.6-10-ºQ) where 250 Q1 <1110, 250 Q2 <1110, 250 <3 < 1225 Qi = flow through turbine i in cubic feet per second KW = power generated by turbine i in kilowattsarrow_forward
