Question

If f(x)= -2x power3+3x power 2+5,find the value of f(1)​

Answer 1

Answer:

1. f(x)=-2x power 3+ 3x power 2 +5
2. find f(1)
3. f(1)= -2×1×1×1+3×1×1+5
4. f(1)=-2+3+5
5. f(1)=1+5
6. f(1)=6

Answer 2

Given:-

$\sf if \: f(1) = - 2 {x}^{3} + 3 {x}^{2} + 5$

To Find:-

Find the value of f(1) = ?

Solution:-

we put the value of f(1) in the place of f(x) .

$\sf f(1) = - 2 \times {1}^{3} + 3 \times {1}^{2} + 5 \\ \\ \sf \implies - 2 + 3 + 5 \\ \\ \sf \implies6$

Hence, the answer is 6.
