Question

Solve this.............

Answer 1

f(x)=7x^2-2x+5
so, f(1)=7-2+5=10
f(-1)=7+2+5=14
f(0)=0+0+5=5
so, f(1)+f(-1)+f(0)=10+14+5=29
is the answer...

Hope u like my process
=====================
$= > \bf \: \: f(x) = 7 {x}^{2} - 2x + 5 \\ \\ = > \bf \: \: f(1) = 7( {1}^{2} ) - 2(1) + 5 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7 - 2 + 5 = 10 \\ \\ = > \bf \: f( - 1) = 7 {( - 1)}^{2} - 2( - 1) + 5 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7 + 2 + 5 = 14 \\ \\ = > \bf \: f(0) = \: 7 {(0)}^{2} - 2(0) + 5 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5 \\ \\ = > \bf \: f(1) + f( - 1) + f(0) \\ \\ \bf = 10 + 14 + 5 = 29$
