4.28 is a decimal and not a mixed number. To write it as a mixed number you keep the 4 and put 28 over 100 then simplify.

4.28= 4 28/100 (simplify)
4 28/100= 4 14/50= 4 7/25

4.28 as a mixed number would be 4 7/25

A) Let f(x) = 4x + 2 and g(x) = 2x^2-4. Find the formula for the composition function gof

ollegr [7]

Answer:

g o f = $g(f(x)) = 32x^2 + 32x + 4$

Step-by-step explanation:

Given

$f(x) = 4x +2$

$g(x) =2x^2 - 4$

Required:

Find g o f

This is calculated as:

$gof = g(f(x))$

$g(x) =2x^2 - 4$

So:

$g(f(x)) = 2(4x+2)^2 - 4$

$g(f(x)) = 2(4x+2)(4x+2) - 4$

$g(f(x)) = 2[ 16x^2 + 16x + 4)] - 4$

$g(f(x)) = 32x^2 + 32x + 8 - 4$

$g(f(x)) = 32x^2 + 32x + 4$

Simplify the following expression 5^2-4/5+2

oee [108]

If <span>(5^2-4) / (5+2) then
=(25 - 4 )/3
= 21/3
= 7

if 4/5 fraction then
</span><span>5^2-4/5+2
= 25 - 4/5 + 2
= 27 - 4/5
= 26 5/5 - 4/5
= 26 1/5
= 26.2</span>
