Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
Answer: square units
Explanation: cubic units are used for volume, square units are used for he base, height, and area of a solid figure
Answer: Yes. True
Step-by-step explanation:
In (-3, -7) , -3 is x and -7 is y.
Now, put those values in the equation.
y = 4x + 5
-7 = (4×-3)+5
-7 = -12 + 5
-7 = -7, which is true
