What is the value of 15 + x2 when the value of x is 3? also there's a tiny 2 above the 15

Answer- 15 to the power of 2 +x2 when x is 3, calculates to the answer of 231.

Method- The tiny 2 is called the exponent, which simply means multiply the 15 by its self 2 times, so 15 times 15, which you get 225, so 225 +(3)2 = 225+6=231. Hope this helps

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
