Answer:
use geogebra app you can install it on your pc
Step-by-step explanation:
First thing first, let find the x value of where P and Q both meet y=5, we know that y=5, and y=2x^2+7x-4, so using transitive law,
Now, to find the gradient of the curve let take the derivative of both sides
Plug in -9/2, let call that point P
Plug in 1, let call that point Q
So the gradient of the curve at point P (-9/2,5) is -11
The gradient of the curve at point Q (1,5) is 11.
The answer is letter choice c
I used a calculator to try to get the answer and i got 40.5, so your answer is most likely C. 41
