Let f(x)=2x^2+x-3 and g(x)=x-1. perform the indicated operation, then find the domain. (f*g)(x) answers: a. 2x^3-x^2-4x+3; domain: all real numbers b. 2x^3+x^2-3x; domain: all real numbers c. 2x^3+x^2+4x-3; domain: negative real numbers d. 2x^2+x-3x+3; domain: positive real numbers i'd appreciate any i can get! i don't want just the answer, i'd like to know the steps too so i can figure out how to do this in the future!

Me with this question, i'm stuck ; ( . gaya owes $75. she plans on paying back her debt at $3 per day. the amount she owes after a given number of days can be represented by y=3x−75. which of the following correctly analyzes the domain of this situation? a) the domain represents time, in days, and since time has to be greater than or equal to 0, the domain is x ≥ 0. b) since 3x−75 has to be greater than 0, the value of x has to be greater than 25. the domain is x > 25. c) the domain represents the amount owed and since this value has to be less than or equal to 75, the domain is x ≤ 75. d) since there are no restrictions placed on the values of x, the domain is all real numbers.

Breanna states that's the domain of the exponential function shown below is {x|x> -4} which of these accurately describes her statement . a breanna correctly determined the domain of the function b breanna should have used the x- interce pt and determined the domain to be {x|x> 5} c breanna did not use the inequality sign , and she should have determined the domain to be {x|x< -4} d breanna did not include -4-4 as part of the domain , and she should have determined a domain as {x|x> -4} e breanna may have confused domain and range , she should have determined the range to be all real numbers
