Answer:
a.) -1 < x < 5
b.) x <= 1
Step-by-step explanation: Domain is the independent variable (x).
For both question a and b, make sure that the number under the square root does not end up being negative. And the denominator of the fractional number is not equal to zero when variable x is being substituted for any value.
a.) y = √ x + 1 /√ 25 − x^2
Domain : -1 < x < 5
That is the minimum value for x is 0 and the maximum value is 4
b. f(x) = (√ 1 − x ) ln x
Domain : x <= 1
That is, x is less than or equal to 1
The maximum value for x is 1. x can be
1, 0, -1, -2, -3, ..........
Hope this helps :D

Answer:
Step-by-step explanation:
Given
Solving (a): Reflect S across y-axis
The rule to reflect across y-axis is:
So, we have:
Hence:
Solving (b): Reflect Q across x and y-axis
The rule to reflect across x-axis is:
So:
The rule to reflect across y-axis is:
So:
Hence:
Answer:
always
Step-by-step explanation:
this product can also be written as a^2 - ab - ab + b^2
which is a^2 - 2(ab) + b^2
a perfect square trinomials equation is
a^2 + 2(ab) + b^2
and this qualifies
