f(x)=x^2+2x+1
Let x = -7
f(-7)=(-7)^2+2*-7+1
= 49 -14+1
= 36
Answer:
find derivative of function
sub in x value of point to find gradient of tangent
put gradient into y=(gradient)x+c
Sub in point and solve for c
you have found the equation of the tangent.
A) 3y - x = 10 is the correct answer! (I just graphed it on Desmos.com)
Solved Correct Answer B ( conjucted with association of y= 5x + 5 - Graphed (0,5)
