State the domain and range for the function f(x) = 2x^2 - 7

2x^2 - 7  

we can plug any values of x into this The domain is All Real x.

The graph will be a parabola opening upwards with a minimum value  when x = 0  and  f(x) will be = -7

so the range is  f(x) <= -7    or  (-∞, -7]

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
