FIRST. find the factors:
X=-5 --> (X + 5) = 0
x = 1--> (X - 1) = 0
x =3 --> (x - 3) = 0
3
NEXT, multiply all the factors:
(x + 5) (x - 1) (x - 3) = 0
-> X3 + x2 - 17x +15 = 0
-> f(x) = x3 + x2 - 17x +15 or
y=x3 + x2
17x + 15
Approximate the real zeros of f(x) = x2 + 3x + 1 to the nearest tenth
<u>C. 2.6,-0.4</u>
<u />
Answer:
3 x 5/6 is 2.5, so 15/6
Step-by-step explanation:
3/1 x 5/6
To find the inverse of a function, firt we let
Now we switch x and y and solve for y .
Adding 25 to both sides
Now we need to get rid of square and for that we take square root on both sides. That is
Therefore, inverse is
