What are the domain and range of the function f(x) = 3x + 5?
domain: (-0, cs); range: (0,0)
O domain: (-3,0); range: (5,0)
O domain (0.co); range: (-0,00)
domain: (5.00); range (-0,00)

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the answer is b

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
