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
If a= 9 then 5a =
Answer:
a = 6 5a=45
Step-by-step explanation:
