- The function, f(x) = –2x² + x + 5, is in standard form. The What are the zeros of the function quadratic equation is 0 = -2x + x + 5, where a = -2, b = 1, and c = 5. The discriminate b2 – 4ac is 41. Now, complete step 5 to solve for the zeros of the quadratic function. f(x) = x + 5 – 2x2? x = -1±/4T -4 5. Solve using the quadratic formula. O x= 1±/41 -4 -b±yb²- 4ac_ x = 2a x = -1±/39 - 4 X = 1±/39 - 4arrow_forwardDifferentiate the given equation below. In(3x³ + 2x – 1)arrow_forwardrefer to imagearrow_forward
- Assume the least square equation is ŷ = 10+20X. What does the value of 10 in the equation indicate?arrow_forwardData were collected from several hospitals about the charge for medical procedures and the popularity of the procedures. The results were used to calculate the model ŷ = -58.25x + 927, where x represents the cost of the procedure in thousands of dollars and ŷ represents the predicted number of procedures performed. Using the model, how much would a procedure cost that is predicted to be performed 400 times? $223,730 ○ $90,472 O $22,373 $9,047arrow_forwardUse the fact that 14 gallons is approximately the same amount as 53 liters to find a mathematical model that relates liters y to gallons x.Then use the model to find the numbers of liters in 5 gallons and 25 gallons.arrow_forward
- Is (7, 7) a solution to the equation y = x?arrow_forwardRewrite the following quadratic function y = x2 + 2x – 77/22 in vertex form by completing the square. State the vertex, the axis of symmetry, the minimum or maximum value, the x- and y-intercepts, the domain, and the range. Sketch the graph. Answer Step-by-steps.
