Question

If $y=4x^2+6$, then match the corresponding value of y for the given values of x.

• A. $y=10$
• B. $y=22$
• C. $y=42$
• D. $y=106$

Answer 1

Given, the equation is :
$y=4x^2+6$
Substituting the values of $x$,
at $x=1$,
$y=4(1{)}^2+6$
$y=4+6$
$y=10$

Similarly, at $x=2$,
$y=4(2{)}^2+6$
$y=16+6=22$,

At $x=3$,
$y=4(3{)}^2+6$
$y=36+6=42$

At $x=5$,
$y=4(5{)}^2+6$
$y=100+6=106$.
