p(x) =5x³-3x²-7x+8
We have given a function p(x)
we have to find p(2)
Step by step explanation
- First step is to write a function and now match with the requirement /need of the question.
- 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
