Answer:
67.9375
Step-by-step explanation:
x+15=19
x=19-15=4
x^3-x^-2+16x^-1 = 4^3-4^-2+16(4)^-1=67.9375
Answer:
Answer is 67.9
Step-by-step explanation:
[tex]{ \sf{x + 15 = 19}} \\ { \sf{x = 4}}[/tex]
function of x:
[tex]{ \bf{f(x) = {x}^{3} - {x}^{ - 2} + 16x {}^{ - 1} }} \\ { \sf{f(4) = {4}^{3} - (4) {}^{ - 2} + 16(4) {}^{ - 1} }} \\ { \sf{f(4) = 67.9}}[/tex]
