2014年9月13日 · It's all real numbers. The domain of any function is simply all the possible numbers you can input for x without violating the rules of math. In the given function f(x) = 3x + 4, you can input any number for x without violating the rules of math, or blowing a hole through the earth's core. However, when you get more complex functions, like those with fractions and square roots, things become a ...

2014年9月18日 · f(x)=3x+4 is a linear function, and so the domain and range for that functions is all real numbers. In fact, the domain and range for any linear function is all real numbers. So, in interval notation: The domain (or possible input(x)-values) is: (-∞,∞) The range (or possible output(y)-values) is: (-∞,∞) *Note the round brackets ( ) …

:. f'(x) = 3 The definition of the derivative of y=f(x) is f'(x)=lim_(h rarr 0) ( f(x+h)-f(x) ) / h So Let f(x) = 3x-4 then; \ \ \ \ \ f(x+h) = 3(x+h) -4 :. f(x+h ...

Question 296771: Problem: Determine whether f(x)=3x^4-5x^2+2 is even, odd, or neither. I automatically want to say "neither" because of that 3x to the fourth power, but I tried plugging "-x" in the equation in place of "x" just to test it.

You can put this solution on YOUR website! put 1 everywhere there is an x f(1)=3(1)^2+3(1)-4 =2

Then the range of #f(x)# is the set of values of #f(x)# over #D#. We can think of this as the valid outputs. To determine the domain and range of a function, first determine the set of values for which the function is defined and then determine the set of values which result from these. E.g. #f(x) = sqrtx# #f(x)# is defined #forall x>=0: f(x ...

The degree of a polynomial is determined by the highest power of #x# in the polynomial. e.g. #f(x) = 2x^5-3x^2+4# The highest power of #x# in f(x) is 5. Hence, degree of f(x) = 5. A polynomial with only a constant, e.g. #P(x) = 5# has a degree of 0 as #5=5x^0#

You can put this solution on YOUR website! If f(x)=3x^2-2x+4, then f(x + h) = 3(x + h)^2 -2(x + h) + 4 =3(x^2 + 2hx + h^2) - 2(x + h) +4
