For the function shown below, find f(3): f(x)=2x^4-8x^2+5x-7
a_sh-v [17]

We have been given the function

f(x)=2x^4-8x^2+5x-7

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

f(3)=2(3)^4-8(3)^2+5(3)-7

Now, we simplify this step by step.

First of all 3^4=81\text{ and }3^2=9. Thus, we have

f(3)=2\times 81 -8\times 9+5(3)-7

Now, we can easily simplify it by PEMDAS

f(3)=162-72+15-7

f(3)=98


Therefore, the value of f(3) is 98.
