H.<br> R(x) = kx – 2x^2 ; R(1/4)<br> R(-1/4)<br> find k.
True [87]

Answer:

k=0

Step-by-step explanation:

R(x)=kx-2x²

R(1/4)=k(1/4)-2(1/4)²=k/4-1/8

R(-1/4)=k(-1/4)-2(-1/4)²=-k/4-1/8

R(1/4)=R(-1/4)

k/4-1/8=-k/4-1/8

k/4+k/4=1/8-1/8

2k/4=0

2k=0

k=0

This means the constant of proportionality would be y = 15x


The answer is C.
