Check the picture below.

is it even?  well, even functions use the y-axis as a mirror, so a pre-image on the right-side, will be a mirror of the image on the left-side, but in this case it isn't so, if you put a mirror right on the y-axis, the left-side will look a bit different.

does it have a zero at x = 0?  well, just look at the graph, is the line touching the x-axis at 0? nope.

does it have an asymptote at 0?  well, surely you can see it right there.

Solve each equation. Some of them may have radicals in their solutions.
Maurinko [17]

Answer: a) 3 and -3 b) 4 and 2

c) 3.5 and 2.5 d) 5.5 and 0.5 e) This is due to the difference in the coefficient of (x-3)² and the value at the right side of each equation.

Step-by-step explanation:

a) 3x²-9 = 0

3x² = 0+9

3x² = 9

Dividing both sides by 3

x² = 9/3

x² = 3

x = √3

x = +3 and -3

b) (x-3)² = 1

Taking square root of both sides to remove the square,

√(x-3)² = √1

x-3 = √1

x-3 = 1 and x-3 = -1 (note that √1 is +1 and -1)

x = 4 and x = 2

c) 4(x-3)² = 1

Dividing both sides by 4 we have;

(x-3)² = 1/4

Taking the square root of both sides to eliminate the square.

√(x-3)² = √1/4

x-3 = √1/4

x-3 = +1/2 and x-3 = -1/2

x = 1/2+3 and x = -1/2+3

x = 3.5 and 2.5

d) 2(x-3)² = 12

Dividing both sides by 2 we have;

(x-3)² = 12/2

Taking the square root of both sides to eliminate the square.

√(x-3)² = √12/2

x-3 = √6

x-3 = 2.5 and x-3 = -2.5

x = 2.5+3 and x = -2.5+3

x = 5.5 and 0.5

e) The answers to questions 1 to 4 has different solutions due to the different value of the coefficient of (x-3)² and also the value at the right hand side of the equations also differs, hence, the reason for the difference in their answers.

She paid $1.375 per pound of strawberries.

<u>What is the unit rate?</u>

When expressed rate as a fraction, a unit rate has a denominator of 1.

Since 4 pounds cost $5.50, 1 pound of strawberries will cost 5.50/ 4 ≈ $1.375.
