Mathematics
1 answer:
Effectus [21]3 years ago
6 0

Answer:

Domain: [-2, 5)

Range: (-3, -1]

General Formulas and Concepts:

<u>Algebra I</u>

Coordinate Planes

  • Domain is the set of x-values that can be inputted into function f(x)
  • Range is the set of y-values that are outputted by function f(x)

Interval Notation

Step-by-step explanation:

According to the graph, our x-values span from -2 to 5. Since x = -2 is a closed dot, it is inclusive; x = 5 is an open dot, meaning exclusive.

Domain: [-2, 5)

According to the graph, our y-values span from -3 to -1. Since y = -3 is an open dot, it is exclusive; y = -1 is a closed dot, meaning inclusive.

Range: (-3, -1]

Find the domain and range of f(x) = 2 square root of x-2
Neporo4naja [7]
f(x)=2\sqrt{x-2}\\\\The\ domain:\\x-2\geq0\to x\geq2\\\boxed{x\in[2;\ \infty)}\\\\The\ range:\\\boxed{y\in[0;\ \infty)}

If\ f(x)=2\sqrt{x}-2,\ then\\\\The\ domain:\boxed{x\in[0;\ \infty)}\\\\The\ range:\boxed{y\in[-2;\ \infty)}

The data shown has a least-squares regression line of y=3.2x−6.4.
Damm [24]

Answer:

1) B. on, 2) D. 19.2, 3) C. 0

Step-by-step explanation:

1) The value of y according to the regression line is:

y = 3.2\cdot (8) - 6.4

y = 19.2

Hence, the point (8,19.2) is <em>on </em>the least-squares regression line.

2) The value of y according to the regression line is 19.2.

3) The residual is the difference between the value from the regression line and the real value. In this case, the residual value is 0.
