Step-by-step explanation:
The equation represents both a relation and a function
<h3>How to determine if the equation represents a relation, a function, both a relation and a function, or neither a relation nor a function?</h3>
The equation is given as
y = x^4 - 3x^2 + 4
First, all equations are relations.
This means that the equation y = x^4 - 3x^2 + 4 is a relation
Next, the above equation is an even function.
This is so because
f(x) = f(-x) = x^4 - 3x^2 + 4
This means that the equation is also a relation
Hence, the equation represents both a relation and a function

Answer:
c
Step-by-step explanation:
1/6. theres only one 2, and theres 6 numbers total.
Let’s simplify!
y = 6(x - 2)² - 3
y = 6(x - 2)(x - 2) - 3
y = 6(x² - 2x - 2x + 4) - 3
y = 6(x² - 4x + 4) - 3
y = 6x² - 24x + 24 - 3
y = 6x² - 24x + 21
Solution:
we have been asked to find
How much more time did Maria spend doing research ?
Maria spends doing research = 30%
and using email = 15% of a day (24 hours)
Time spent on research = 30% of 24 = 
Time spent on checking email = 15% of 24 = 
so, 
Hence , Maria spends 3.6 hours more on doing research than checking email.
