Let g(x) = -x^2 + x. Find g(-10)

g(-10) = 90

Step-by-step explanation:

g(x) = -x^2 + x

= -(-10^2) +(-10)

=10^2-10

=100-10

=90

y = 42x + 2

Step-by-step explanation:

The equation of a line is expressed as y = mx+b

Slope = y2-y1/x2-x1

Slope = 128 - 2/3-0

Slope m = 126/3

Slope = 42

Since the y intercept is (0, 2), hence b = 2

Get the equation;

Recall that y = mx+b

y = 42x + 2

This gives the required equation
