find the zeros of the polynomial from factored form

What is the degree of the polynomial function
P(x)=3x⁴-7x²-2x⁷-x+4?

• 4
• 7
• 2
• 1

What is another way to say "where a function crosses the x-axis"?

• x-intercept
• zero
• root
• all of these.

Select all the graphs which show even degree functions.

What is the standard form of the polynomial,
7x - 125 - 6x⁴ + 14x²

• 125 + 7x - 14x² +6x⁴
• 6x⁴  -14x² - 7x +125
• 125 + 14x² + 7x  - 6x⁴
• -6x⁴+ 14x² + 7x - 125

f(x)= x²(x – 2)³(x – 7)

Find and select each real zero and its multiplicity

• 0 (Mult of 2), 2 (Mult of 3), 7 (mult 1)

• 2 (Mult of 3), 7 (mult 1)

• 0, 2, 7

• 2 (mult of 2), 7 (mult of 3)

convert from factored from to standard

y= (x+2)(x+5)(x-3)

• y= x³+ 6x² -11x +30

• y= x³ - 30

• y=x³+4x²-11x-30

• y= 3x³+10x²-15

•  $-4,\ 0,\ 5$  

•  $-4,\ 3,\ 5$  

•  $-5,\ -3,\ 4$
