f(x) = x^5 - 2x^3 + 12; find f(3) and f(-2)

Sagot :

Answer:

f(3)=201

f(2)=-4

Step-by-step explanation:

Plug in each value for x

[tex]3^{5} -2(3)^{3} +12[/tex]

[tex]243-54+12=201[/tex]

[tex]-2^{5} -2(-2)^{3} +12[/tex]

[tex]-32+16+12=-4[/tex]

Answer:

f(3) = 201

f(-2) = -4

Step-by-step explanation:

[tex]f(x) = x^5 - 2x^3 + 12[/tex]

[tex]f(3) = (3)^5 - 2(3)^3 + 12[/tex]

[tex]\implies f(3) = 243 - 54 + 12[/tex]

[tex]\implies f(3) = 201[/tex]

[tex]f(-2) = (-2)^5 - 2(-2)^3 + 12[/tex]

[tex]\implies f(-2) = -32+16 + 12[/tex]

[tex]\implies f(-2) = -4[/tex]
