F(x) = { -2x -1, x ≤ 2
Degger [83]

Answer:

Use the appropriate entry method for piecewise functions for the graphing calculator of interest.

Step-by-step explanation:

For Desmos, the entry looks like ...

f(x) = {x ≤ 2: -2x-1,-x+4}

_____

For a TI-84 calculator, the entry may look like ...

Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)

The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.

Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:

... (0≤X)(X<2)

Answer:

  • 9x⁵

Step-by-step explanation:

<u>Use properties of exponents:</u>

  • <u />a^{b} a^{c} = a^{b+c}, (a^{b} ^)^{c} = a^{bc}, 1/a^{-b}  = a^{b}

<u>Simplify the given expression:</u>

  • 3⁴⋅x⋅(3/x²)⁻² =
  • 3⁴·x·(3x⁻²)⁻² =
  • 3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
  • 3⁴⁻²·x¹⁺4 =
  • 3²·x⁵ =
  • 9x⁵
