Question

Which function has the values f(4)=-15 and f(7)=57

A) f(x)=14x-71
B) f(x)=24x-1361
C) f(x)=24x=360
D) f(x)=24x-111

Answer 1

D. f(x) = 24x-111

Explanation:

A) f(x)=14x-71

f(4) = 48-71 = -23 NO

B) f(x)=24x-1361

f(4) = 96 - 1361 NO

C) f(x)=24x-360 [-360, not =360]

f(4) = 96 - 360 NO

D) f(x)=24x-111

f(4) = 96 - 111 = -15 YES

f(7) = 168 - 111 = 57 YES
