Answer:
x = all real values
y = all real values
Step-by-step explanation:
The domain is the input values
f(x) = 4x+52 which is a line
The input or x values can be any value so the domain is all real values of x
The range is the output values
f(x) = 4x+52 which is a line
The output or y values can be any value so the domain is all real values of y
This is a perfect square parabola
f(x) = (2x + 5)^2
the graph will be a parabola opening upwards and will touch the x-axis at x = -2.5
The signs mean greater than, less than or equal.
I can’t see the “students work”. But the answer would be 250 words in 5 minutes.
Here’s how you would set up the equation:
25x(5*2)=
So your first step would be to multiply 5 and two because they’re in parenthesis, which would be 10.
So now you have:
25x10
25 times 10 is 250.
Hope that makes sense and helps! :)
Y = kx where k is a constant
27 = k*9
k = 27/9 = 3
required variation is y = 3x
