Answer 2

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

p(x) =5x³-3x²-7x+8

We have given a function p(x)

we have to find p(2)

Step by step explanation

1. First step is to write a function and now match with the requirement /need of the question.
2. Now ,put the value in the function whatever the question demand .

Demand of Question is to find p(2) and now we match with the original Question=>p(x)

here ,2 to find and in the function is x .so, just simply put 2 in the given function.

p(x)=5x³-3x²-7x+8

p(2)=5(2)³-3(2)²-7(2)+8

p(2)=5×8-3×4-7×2+8

p(2)=40-12-14+8

p(2)=28-6

p(2)=22

∴Value of p(2) is 22
