Answer 1

Answer:

(2, -3), (3, -3)

Step-by-step explanation:

y = x^2 - 5x + 3

y = -3

x^2 - 5x + 3 = -3

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0

x - 3 = 0 or x - 2 = 0

x = 3 or x = 2

We are given y = -3.

Answer: (2, -3), (3, -3)

Answer 2

Answer:

(2, -3) , (3, -3)

Step-by-step explanation:

One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,

$f(x)=x^2-5x+3$

Set this equation up, and solve to find the value of (x) that satisfies this requirement:

$f(x)=x^2-5x+3=-3$

Inverse operations,

$x^2-5x+6=0$

Factor, rewrite the quadratic equation as the product of two linear equations,

$(x-2)(x-3)=0$

Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

(2, -3), (3, -3)
