云炎莉5235如图,在平面直角坐标系中,直线y= - 3/4x+3分别于x轴,y轴交于点A和点B.二次函数y=ax^2 - 4ax+c的图像
晏尹幸15141584551 ______ (1).由于B点,x=0,则y=3.所以B点坐标为(0,3).因二次函数抛物线经过B点,故满足解析式,得:c=3.又因该二次函数经过C(-1,0),所以又可得0=a+4a+3,所以a=-3/5.所以该届二次函数解析式为y=-3/5x^2+12/5x+3.(2).由上问可得定点坐标为(...

云炎莉5235高中数学 函数y=e∧(x+1)的图像必经过的定点是 -
晏尹幸15141584551 ______ e^x函数本来就是一个确定的函数,图像是与Y轴交于(0.1)的一条确定的单调递增的光滑的曲线,你说的这个函数只是将图像整体向左平移一个单位,平移之后的点是(-1.1)
云炎莉5235若函数f(x)的图像与函数y=[e^x+e^( - x)]/[e^x - e^( - x)]的图像关于直线y=x对称,则f(X)=? -
