The first steps in writing f(x) = 4x2 + 48x + 10 in vertex form are shown. f(x) = 4(x2 + 12x) + 10 = 36 what is the function written in vertex form? f(x) = 4(x + 6)2 + 10 f(x) = 4(x + 6)2 – 26 f(x) = 4(x + 6)2 – 134 f(x) = 4(x + 6)2 + 154

f(x) = 4(x + 6)² – 134

Step-by-step explanation:

To write an equation in vertex form, we first factor out the GCF of the first two terms.  For 4x² and 48x, this is 4:

f(x) = 4(x²+12x)+10

Next we complete the square.  The value of b inside parentheses is 12; we take half of that and square it:

(12/2)² = 6² = 36

We add this inside parentheses.  However in order to preserve equality, we must subtract this value as well.  Since the terms inside parentheses are being multiplied by 4, we multiply the 36 we subtract by 4 as well:

f(x) = 4(x²+12x+36)-4(36)+10

Simplifying, we have

f(x) = 4(x²+12x+36)-144+10

Combining like terms,

f(x) = 4(x²+12x+36)-134

Next we write the trinomial in parentheses as a perfect square:

f(x) = 4(x+6)²-134

its C

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.
