Find the points of intersection of the graphs involving the following pair of functions.
jeka57 [31]

Answer:

The point of intersection is ( \frac{-1\pm\sqrt{5}}{2}, 0)

Step-by-step explanation:

f(x) = 2x^2 + 3x - 3 and g(x) = - x^2

By equating them

2x^2 + 3x - 3 = -x^2

3x^2 + 3 x - 3 =  0

x^2 + x - 1 = 0

x^2 +x - 1 = 0 \\\\x = \frac{-1\pm\sqrt{5}}{2}

Consider the function c(x)=(x+3) (x-5)2 what are the zeros of c(x)
vekshin1

Answer:

The zeroes would be -3 and a double root at 5.

Step-by-step explanation:

We can find this by first expanding the function.

c(x) = (x + 3)(x - 5)^2

c(x) = (x + 3)(x - 5)(x - 5)

Then we can solve for the zeroes by setting each parenthesis equal to 0 and solving.

x + 3 = 0

x = -3

x - 5 = 0

x = 5

x - 5 = 0

x = 5
