Step-by-step explanation:
Now we find the x and y intercept of f(x)
For x-intercept: Put f(x)=0 and solve for x
So, x=3.92 (Just before 4 on x-axis)
For y-intercept: Put x=0 and solve for f(0)
So, y=3 (Passes through y-axis at 3)
End Behavior: Third degree function
Possible graph of the f(x). Please see the attachment.

Answer:
4 3/8 cups of baking soda
Step-by-step explanation:
1 3/4 cups of baking soda are needed to make 1 batch of a homemade cleaning product,
Cups of baking soda : batches of homemade cleaning
1 3/4 cups : 1 batch
How many total cups of baking soda I needed to make 2 1/2 batches of the cleaning product?
Let x = total cups of baking soda needed
Cups of baking soda : batches of homemade cleaning
x cups : 2 1/2 batches
Equate the ratios
1 3/4 cups : 1 batch = x cups : 2 1/2 batches
7/4 ÷ 1 = x ÷ 5/2
7/4 × 1/1 = x * 2/5
7/4 = 2/5x
Divide both sides by 2/5
x = 7/4 ÷ 2/5
= 7/4 × 5/2
Cross product
x = 35/8
= 4 3/8 cups of baking soda
