Answer:
Option (3)
Step-by-step explanation:
Given function is,
f(x) = x⁴ + x³ - 2x²
= x²(x² + x - 2)
= x²(x² + 2x - x - 2)
= x²[x(x + 2) - 1(x + 2)]
= x²(x + 2)(x - 1)
So the factored form of the polynomial function is,
f(x) = x²(x + 2)(x - 1)
For x - intercepts,
F(x) = x²(x + 2)(x - 1) = 0
x = -2, 1
This function has even multiplicity = 2 at x = 0.
Therefore, graph of the function will touch the x-axis at x = 0
And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.
Option (3) will be the correct option.
Answer:
442
Step-by-step explanation:
624-183= 442 he needs to drive 442 miles more
Supplementary angles are those which sum upto 180°
Complementary are those which sum to 90°
so if you know one angle, you can find other.
Answer:
132
Step-by-step explanation:
calculator says so.
A line = 180 degrees
so z = 180 - 124
z = 56
