1. A cab driver charges a flat rate of $7 for the first mile driven and $2 for every mile after that. If thecost of the cab ride is modeled by the expression 7 + 2(x - 1). What does (x - 1) represent?

Answers

Answer 1
Answer:

Answer:

The number of miles driven after

Step-by-step explanation:

is how much they charge flat out

2 dollars for each mile after the first

x-1 tells you how many miles they have driven after the first

Identify the vertex, axis of symmetry, maximum orminimum, and domain and range of the function
2x² – 5x + 3 = m(x)

Answers

Answer:

  • vertex: (1.25, -0.125)
  • axis of symmetry: x = 1.25
  • minimum: -0.125
  • domain: all real numbers
  • range: y ≥ -0.125

Step-by-step explanation:

For quadratic ax² +bx +c, the axis of symmetry is x = -b/(2a). For your function, a=2, b=-5, c=3 and the axis of symmetry is ...

  x = -(-5)/(2(2)) = 5/4 = 1.25

The vertex is on the axis of symmetry. The y-value there is ...

  m(5/4) = (2(5/4) -5)(5/4) +3 = (-5/2)(5/4) +3 = -25/8 +24/8 = -1/8

The vertex is (5/4, -1/8).

The axis of symmetry is x = 5/4.

The leading coefficient is positive, so the parabola opens upward. The vertex is a minimum.

The minimum is -1/8.

The function is defined for all values of x, so ...

the domain is all real numbers.

Values of y can only be -1/8 or greater, so ...

the range is y ≥ -1/8.
