Answer:
Observe that f(x) is a continuous function when 
because is a polynomial. The possible problem may occur in x=1.
Then, f(x) is discontinuous in x=1 if the limits of f to the right and the left of 1 exist and are different or if some of those limits doesn't exist.
Let's calculate the limits:
Since, 
then f(x) is discontinuous in x=1.
Answer:
translation
Step-by-step explanation:
translation is just the movement of a shape, also stays the same size and way
Answer:
y=2x+7
y=4x+7
y=5x
Step-by-step explanation:
substitute the numbers for the variables in the form y=mx+b
First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2
Answer:
40
Step-by-step explanation:
x= 4 and y = 4
3x + 7y
3(4) + 7(4)
12 + 28
=40
