On the coordinate grid, the graph of y = 3x - 1 + 3 is What is the domain of the graphed function?
shown. It is a translation of y = 3x.
Ty
{x 1 O {y|1 < y<5}
{x x is a real number}
O {yly is a real number}
6
5

Step-by-step explanation:

the domain is the interval or set of all valid input values (values of x).

while the range is the interval or set of all valid result values (y values).

so, we don't need to look at the answer options dealing with y. the domain only concerns x.

and when you look at the graph it shows you that every number on the x-axis from all the way to the left to all the way to the right is valid (from -infinity to +infinity).

and the function itself (the cubic root of x) did not provide any theoretical limits. you can take the cubic root from any number, positive or negative.

therefore, the third answer option is correct (all x, where x is a real number).

step-by-step explanation:

(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.
