Graphing Quadratic Functions
f(x) = 2r2 - 5x + 1, -1 (x, y)
f(x) = -2x2 + 3x + 4,-2.5 (x, y)
(d) f(x) = -4x² + 4x - 1,-1 (x, y)

I don’t understand anything can anyone help?

factor trees are nice.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
