The sale price of apples at a local grocery store is $1.35 for the first kind and $1.10 for each additional pound. Which function rule shows how the cost of apples,y, depends on the number of pounds, x?

If the first pound is worth 1.35, then this number is constant, so it will be unchanged. The second and subsequent ones change, so they must contain x.

Therefore
y=1.35 + (1.10 x X)

Wow

woah

14. The sale price of apples at a local grocery store is $1.35 for the first pound and $1.10 for each additional pound. Which function rule shows how the cost of apples, y, depends on the number of pounds, x?

y = 1.10(x – 1) + 1.35
y = 1.10x + 1.35
y = 1.35x + 1.10
y = (1.10 + 1.35)x

The correct answer is:

y = 1.35 + 1.10(x-1)

Explanation:

The cost of the first pound of apples is $1.35, which is a constant value. For each additional pound, the cost is $1.10, so we need to multiply this by the number of additional pounds, which is x-1 (since we're already accounting for the first pound at $1.35). Putting this together, we get:

y = 1.35 + 1.10(x-1)

Which function rule represents the data in the table?
x
–3
–2
–1
0
1
y
1
–2
–5
–8
–11
y = –3x – 8
y = (Image: one-third)x – 8
y = (Image: one-third)x + 8
y = 3x + 8

The correct answer is:

y = -3x - 8

Explanation:

Looking at the table, we can see that as x increases by 1, y decreases by 3. This means we have a slope of -3, which is the coefficient of x in our function rule. To find the y-intercept, we can see that when x = 0, y = -8. Putting this information together, we get:

y = -3x - 8

y = x² + 5

To determine which quadratic rule represents the given data, we can plot the points on the coordinate plane and look for a parabolic shape.

Doing so, we can see that the graph has a downward opening parabolic shape. This means that we're looking for a quadratic rule with a negative leading coefficient.

From the given choices, we can see that only one equation has a negative coefficient on the squared term:

y = -x² + 5

Thus, this is our answer.
