Which statement is true regarding the graphed functions?

EastWind [94]

Answer:

f(0) = g(0)

Step-by-step explanation:

if a function h(x) passes through [a,b] then it can be said that h(a)=b.

given that, g(x) passes through (-2,0) and (0,4)

so, g(-2)=0, g(0)=4.

f(x) passes through (0,4) and (2,0)

so, f(2)=0, f(0)=4.

therefore, f(0)=g(0)=4.

so, first option is correct.

Solve for y

x+4 = -5y

$y=- \frac{x + 4}{5}$ which is the inverse

Find the limit of the function by using direct substitution. limit as x approaches four of quantity x squared plus three x minus

Yuliya22 [10]

$\lim_{x \to 4} f(x)=x^2+3x-1$
just subsitute
f(4)=4²+3(4)-1
f(4)=16+12-1
f(4)=28-1
f(4)=27

it approaches 27 as x approaches 4
