Answer:

Step-by-step explanation:

Given

y = 2x² - kx + 3

with a = 2, b = - k and c = 3

Since the curve touches the x- axis at one place then the roots are real and equal and the discriminant for this condition is

b² - 4ac = 0, that is

(- k)² - (4 × 2 × 3) = 0

k² - 24 = 0 ( add 24 to both sides )

k² = 24 ( take the square root of both sides )

k = ± $\sqrt{24}$ = ± 2 $\sqrt{6}$

k = 2 $\sqrt{6}$ or k = - 2 $\sqrt{6}$ → E
