Question

Which of the following functions has the largest value when x = 5?

p(x) = 2x2 + 4x + 11
h(x) = 4x
s(x) = 10x

p(x)
h(x)
s(x)
All the functions are equal at x = 5.

Answer 1

\[p(5) = 2.5^{2} + 4.5 + 11 = 81\]

Answer 2

plug 5 for x in each equation and solve
\(\bf\color{blue}{p(x) = 2*5^2 + 4*5 + 11}\)

Answer 3

p(x)

I'm assuming 2x2 is squared which would make p(x) 2*5^2 + 4*5 + 11
2*5 =10^2 = 100
100+ 20 + 11 = 131

Answer 4

p(5) = 131

Answer 5

\(\bf\color{red}{h(x) = 4*5}\)

Answer 6

OK thanks you all

Answer 7

\(\bf\color{green}{s(x) = 10*5}\)

Answer 8

P(x) has the largest ending value...... so its A?

Answer 9

\(\bf\color{blue}{p(x) = 2*5^2 + 4*5 + 11}\\5^2=25\\2*25=50\\50+4*5+11\\4*5=20\\50+20=70\\70+11=81\)
