Hello!
A function is that y only has 1 solution for every x
-3x + 8 = y is a function because it only has one y value for every x
y = x^2 + 3 is a function because it has only one y value for every x
y^2 = x is not a function because it has two y values for x = 4
Hope this helps!
A.

B.

It's a minimum, becuase
.
C.
The axis of symmetry is
. So, in this case, it's
.
Please excuse my dear aunt sally or pemdas
Answer: 2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x) [Work out the brackets]
15x-10=0+6+2x [Solve]
15x-10=16+2x [Convey the terms]
15x-2x=16+10 [Add up the same terms and calculate]
13x=26 [Divide both parts]
x=2
If the function f(x) is translated 7 units right and 8 units up, then the equation of h(x) is h(x) =
+ 8
The given function is
f(x) = 
Here f(x) is translated 7 units right and 8 units up
The translation is the process of changing the coordinates of the shape in the graph
The given function is
f(x) = 
First the function is translated 7 units right
Then the function will become
f(x) = 
Then the function is translated 8 units up
Then the function will become
h(x) =
+ 8
Hence, if the function f(x) is translated 7 units right and 8 units up, then the equation of h(x) is h(x) =
+ 8
