Question

Which of the following is a point on the graph as described by the function y=(2x+1)^2−4 ?(1 point)

Answer 1

wrong

Answer 2

To determine a point on the graph of the function y=(2x+1)^2−4, we need to choose a specific value of x and then calculate the corresponding value of y.

Let's say we choose x=0:

y = (2(0) + 1)^2 - 4
y = (1)^2 - 4
y = 1 - 4
y = -3

Therefore, the point on the graph when x=0 is (0, -3).

Answer 3

Let's try to find the correct point on the graph of the function y=(2x+1)^2−4.

Let's choose x=2:

y = (2(2) + 1)^2 - 4
y = (4 + 1)^2 - 4
y = (5)^2 - 4
y = 25 - 4
y = 21

Therefore, the point on the graph when x=2 is (2, 21).
