Answered by answersmine AT 22/10/2019 – 03:50 AM Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;x^2+14x+41=0x^2+14x=-41but;c=(b/2)^2and b=14hence;c=(14/2)^2=49substituting the value of c in the expression we get:x^2+14x+49=-41+49x^2+14x+49=8(x+7)^2=8this can be written in vertex form;h(x)=a(x-h)^2+kwhere:(h,k) is the vertex;thus(x+7)^2=8h(x)=(x+7)^2-8hence the vertex will be at the point:(-7,-8) Post your answer

## Determine whether the function is linear or quadratic. identify the quadratic, linear, and constant terms y= (x-5)(5x+4)-5x^2

Linear means that it is 1st degree, means it has x¹ basically the highest number is 1 for the power of the placeholder quadratic means it is 2nd degree, means it has x² in it so expand and simlfiy(x-5)(5x+4)-5x²=5x²-21x-20-5x=-21x-20 so y=-21x¹-20it’s linear because the squared terms cancel each other out
