Given the function that g(x) = 2x² − 5x + 1, find each of the following.
-
a) g(0)
b) g(-2)
c) g(4)
d) g(-x)
e) g(1 – t)


Sagot :

Step-by-step explanation:

g(x) = 2x² − 5x + 1

a) g(0)

g(0)=2[tex](0)^{2}[/tex]-5(0)+1

      =1

b) g(-2)

g(2)=2[tex](-2)^{2}[/tex]-5(-2)+1

    =8+10+1

    =19

c) g(4)

g(4)=2[tex](4)^{2}[/tex]-5(4)+1

   =32-20+1

   =11

d) g(-x)

g(x) = 2x² − 5x + 1

g(-x)=2[tex](-x)^{2}[/tex]-5(-x)+1

   =2[tex]x^{2}[/tex]+5x+1

e) g(1 – t)

g(x) = 2x² − 5x + 1

g(1-t)=2[tex](1-t)^{2}[/tex]-5(1-t)+1

     =2[tex]t^{2}[/tex]+t-2
