Question

find the value of each polynomials for the indicated value of variables:
1.p[x]=4xsquare-3x+7atx=1
2.q[y]=2ycuboid-4y=root11aty=1

Answer 1

Is the question correctly written? I hope so.

$p[x] = 4 x^{2} - 3 x + 7 \ at \ x = 1 \\ \\ p[at\ x=1] = 4*1^2 - 3 * 1 + 7 = 4 - 3 + 7 = 8 \\ \\ q[x] = 2 y^3 - 4 y - \sqrt{11} \ at \ y = 1 \\ \\ q [ at\ y = 1 ] = 2 * 1^3 - 4 * 1 - \sqrt{11} = -2 - \sqrt{11}$
