Step-by-step explanation:
f(x) = 2x² + x - 3
f'(x) = 4x + 1
f'(x) = 4(-1) + 1 = -3 slope
f(x) = 2(-1)² + (-1) - 3 = -2
(-1, -2)
-2 = -3(-1) + B
B = -5 y intercept
y = -3x - 5
f(x) = 1/x² = x⁻²
f'(x) = -2x⁻³
f'(-2) = -2(-2)⁻³ = -2/-8 = 1/4 slope
y = 1/4x + B
1/4 = 1/4(-2) + B
B = 3/4
y = 1/4x + 3/4
A=2B
B=B
C=A-2=2B-2
A+B+C=98
5B-2=98
5B=100
B=20
Thus A= 2B = 40
C=38
Nothing much wrong only calculation mistakes
