WebFeb 3, 2024 · You can solve for y with the same substitution, but since the quadratic describes a curve, it could intercept the y-axis at 0, 1, or 2 points. This means you may end up with 0, 1, or 2 answers. Example 4 : To find the y-intercept of y 2 = x + 1 {\displaystyle y^{2}=x+1} , substitute x = 0 and solve the quadratic equation . Web1) Find real numbers a, b, and c so that the graph of the function y = a x 2 + b x + c contains the points (− 1, 4), (2, 3) and (0, 1). Solve the following systems of equations using matrices (row operations). If the system has no solution say that it is inconsistent. 2) ⎩ ⎨ ⎧ x + y − z = 6 3 x − 2 y + z = − 5 x + 3 y − 2 z = 14

WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c … WebFeb 3, 2024 · Answer: y = 4*0.5^x. Explanation: First we'll use the point (1,2) to help isolate c in terms of 'a' y = c*a^x. 2 = c*a^1 ... plug in (x,y) = (1,2) 2 = c*a. c = 2/a-----The use the last equation mentioned above, along with the second point (2,1) to help determine the value of 'a' y = c*a^x. y = (2/a)*a^x .... replace c with 2/a. y = 2*a^(-1)*a^x ... WebWolfram Alpha calls Wolfram Languages's D function, which uses a table of identities much larger than one would find in a standard calculus textbook. It uses well-known rules such as the linearity of the derivative, product rule, power rule, chain rule and so on.
