restrict the domains of quadratic functions and absolute value functions, because these functions are
functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are
functions, so their domains
to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
It's probably D but... I'm not sure so....
Answer:
the function f (x) x. f (x)- 32
Answer: B, D, and maybe E. Check my explanation for 'E'
Step-by-step explanation:
There are a few ways of visualizing the expression, but Ill try to show it to easiest way possible.
Notice nothing was changed because of the property of exponents. An exponent to a power means to multiply them. A thing you should remember for all future cases is that the one-half power means square root. It is the exact same thing. Therefore the new expression I created is the square root of 'x' cubed.
A:) This would be equivalent to x^2/3
B:) This is equivalent to x^3/2 because the square root is the 1/2 power to the power of 3.
C:) This would be equivalent to x^2/3
D:) This is equivalent to x^3/2 because the square root is the 1/2 power, but multiplied by the power under the radical.
E:) If this answer is to the third power, then it is equivalent. I cannot tell from this picture.
Answer:
3 terms
Step-by-step explanation:
In this problem, we are given an expression of a quadratic function of a single variable x as x² - 3x + 7.
Now, we have to find the number of terms included in the above-given expression.
The expression includes two x terms and one constant term.
Therefore, the whole expression has total ( 2 + 1 ) = 3 terms. (Answer)
