Answer:
(4a - 9)(4a + 9)
Step-by-step explanation:
Every value in the equation has a square root
The square root of 16 is 4
The square root of a^2 is a
The square root of 81 is 9.
To factor you split the equation by the square roots. For 81, since the original value is negative, one of the roots must be negative so when you multiply it back out to the original, it stays the same.
You can check your answer this way too.
(4a -9)(4a + 9)
= 16a^2 + 36a - 36a - 81
= 16a^2 - 81
I hope this helps!
Answer:
Y intercept is 275. X intercept is 125.
Step-by-step explanation:
The y intercept is where the line meets the y axis. The x intercept is where the line meets the x axis. You just have to look at those.
A and C are linear equations. A linear equestrian is an equation where the exponent has a term of one and the equation results in a straight line. The function changes at a common rate.
B and D are not linear because the power of their exponents are 3 and 2 respectively making them exponential.

Given:
To find:
The domain of the given function.
Solution:
Domain is the set of input values or x-values.
In the given function, the x-coordinates of ordered pairs are 3, 6, -1, 5 and -4. So, domain is the set of these values in ascending order.
The set builder form of domain is
Therefore, the correct option is C.
