Answer:
The equation 2x+7=0 can be used to find a zero of the function. The graph intersects the y-axis at 49
Step-by-step explanation:
The other statements are not correct because since (2x+7)^2 gives the polynomial function y=4x^2 +28x + 49, there are "two" answers, but it is the sa,e answer of -7/2. The graph also does not have a double root at -7/2, that is the x-intercept

Answer:
Step-by-step explanation:
the expression we have is:
to solve we need to develop the square binomial
with the following formula:
So we have:
and the expression now is:
developing multiplications to remove parentheses:
joining like terms:
This expression can be simplified so it becomes:
(3x^2 - 4) - (2x - 1)
3x^2 - 2x - 3
