There is a typo in your problem statement.

There should be "something" following "^" and before the "-" sign.

Re: Algebra

Find the domain of the following functions and express the answer in interval notation..

A. f (x) =4x^2- 7x+3
b. g (x) = 10/x+7
c f (x) =^4x-16
d. g (x) = 2x/x-3
e. f (x) = 3x-9

All work must be shown and calculations..

Assuming 4x^2 - 7x + 3 = 0 ;
are you able to solve for x?
If not, you need classroom help.

Hello,

Could someone be so kindy to help me by 1:00pm?

Find the domain of the following function functions and express the answer in interval notation

a. F (x) =4x^2-7x+3

b. g (x)= 10/x+7

c. f (x) =The squares root of 4x-16 kind of like a check over this.

d. g (x) =2x/x-3
e. f (x) = 3x-9

Re: Algebra

Start with "All Real Numbers" and see what you need to discard. What doesn't work. What produces nothing or some number other than a Real Number?
