The graphs below have the same shape. What is the equation of the red graph?
arsen [322]

Answer:

D

Step-by-step explanation:

The red graph is vertically shifted from the blue graph. Let's understand horizontal and vertical shifts.

If we have a graph of f(x)=x^2, then

  • f(x) + a is a units shifted vertically up
  • f(x) - a is a units shifted vertically down
  • f(x-b) is b units shifted horizontally right
  • f(x+b) is b units shifted horizontally left

Since the red one is vertically shifted 3 units up (compared to blue graph), the equation would be:

g(x)=f(x)+3\\g(x)=x^2 + 3

Correct answer is D

In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B.
Gwar [14]

Let us assume number of points scored by Team B = b points.

Number of points scored by Team A 5 fewer than twice as many points as Team B, that is "5 less than 2b" = (2b-5) points .

Team C scored 80 more points than Team B, that is " 80 more than b" = (b+80) points.

Total number of points scored by all teams = 983 points.

Therefore, we can setup an equation:

<h3>(2b-5) + b + (b+80) = 983.</h3>

Therefore, an equation to represent this scenario using the variable b to represent Team B’s total points is (2b-5) + b + (b+80) = 983.
